Griddled Lamb Chopped Cheese with Whipped Feta and Pickled Fresnos

This is a griddle sandwich in the chopped cheese format — meat and onions chopped together on the flattop, cheese melted in, piled into a split roll — but built with ground lamb, warm spice and a sharp feta sauce instead of the deli standard. It cooks in about four minutes a sandwich once your mise is set, which makes it a reasonable line item for a truck, a bar kitchen or a lunch counter.

The pickled chilies are not optional. Lamb and feta both bring fat and salt; the pickle is what keeps the third and fourth bite interesting.

Yield

Makes 8 sandwiches, each about 6 oz (170 g) of cooked meat mixture on a 7–8 inch roll.

Ingredients

Lamb mixture

Ingredient	Amount
Ground lamb (80/20 if you can get it)	3 lb (1.36 kg)
Yellow onion, small dice	2 large (about 1 lb / 450 g)
Garlic, minced	6 cloves
Ground cumin	1 Tbsp
Ground coriander	2 tsp
Sweet paprika	2 tsp
Aleppo pepper (or 1 tsp crushed red pepper)	1 Tbsp
Ground cinnamon	1/2 tsp
Kosher salt	1 Tbsp, plus to taste
Black pepper	2 tsp
Tomato paste	2 Tbsp
Neutral oil	as needed

Whipped feta

Ingredient	Amount
Feta, crumbled	12 oz (340 g)
Plain full-fat yogurt	1 cup (240 g)
Lemon juice	2 Tbsp
Garlic, grated	1 small clove
Olive oil	3 Tbsp
Cold water	2–4 Tbsp, to loosen

Makes about 2 1/2 cups — roughly 5 Tbsp per sandwich.

Quick pickled Fresnos

Ingredient	Amount
Fresno chilies, sliced into thin rings	8 oz (225 g)
White wine vinegar	1 cup (240 ml)
Water	1/2 cup (120 ml)
Sugar	2 Tbsp
Kosher salt	1 Tbsp

Build

Ingredient	Amount
Hero, hoagie or Turkish-style rolls	8
Sliced provolone or low-moisture mozzarella	16 slices
Butter, softened, for the rolls	about 4 Tbsp
Shredded iceberg or romaine	about 4 cups
Ripe tomato, sliced thin	2 medium
Mint or parsley leaves, torn	1 cup, loosely packed

Method

1. Pickle the chilies. Pack the sliced Fresnos into a quart container. Bring the vinegar, water, sugar and salt to a simmer until dissolved, pour over hot, and let cool uncovered. They are usable in about an hour and better the next day. Refrigerate.
2. Whip the feta. Blend the feta, yogurt, lemon juice and garlic in a food processor until smooth, then stream in the olive oil. Add cold water a tablespoon at a time until it is thick but spoonable — it should hold a soft ridge, not run. Taste before adding salt; feta brands vary a lot. Refrigerate in a squeeze bottle or piping bag.
3. Season the lamb. Mix the ground lamb with the garlic, cumin, coriander, paprika, Aleppo, cinnamon, salt, pepper and tomato paste. Do not overwork it. Let it sit refrigerated at least 30 minutes so the spices hydrate; overnight is better if your prep day allows.
4. Cook the onions. Film a flattop or heavy skillet with oil over medium-high heat. Cook the diced onion with a pinch of salt until it takes on color at the edges but still has bite, about 5–7 minutes. Pull and hold. Doing the onions separately keeps them from steaming the meat during service.
5. Cook to order. For one sandwich: oil the griddle, drop about 6 oz (170 g) of the lamb mixture in a loose patty, and leave it alone for 2 minutes to crust. Add about 1/4 cup of the cooked onion, then chop and fold everything together with two bench scrapers or a spatula until the meat is broken up and cooked through. USDA guidance is to cook ground lamb to an internal temperature of 160°F (71°C) — check with a thermometer until you know what the pile looks like at that point, and follow your local health department's rules for cooking and holding.
6. Melt the cheese. Shape the chopped meat into a roll-length rectangle, lay 2 slices of cheese over it, and cover with a dome or a splash of water under a lid for about 30 seconds.
7. Toast and build. Butter the split roll and press it face down on the griddle until golden. Line the bottom with lettuce, tomato and a few mint leaves, slide the meat-and-cheese slab on top, stripe generously with whipped feta, and finish with a heavy pinch of pickled Fresnos and a little of their brine. Close, press, cut on the bias, wrap in paper.

Running it as a menu item

Prep ahead. The feta sauce and the pickles both hold well under refrigeration and are better made a day in advance. The seasoned lamb is a day-before item. Onions can be cooked, cooled and refrigerated in a shallow pan.

Portion the meat before service. Scale the seasoned lamb into 6 oz (170 g) pucks on a parchment-lined sheet tray, stacked with parchment between layers. It removes the slowest step from the line.

Don't hold the cooked meat long if you can avoid it. Chopped lamb dries out and the cheese goes rubbery. If your volume forces a hot hold, hold the cooked lamb-and-onion mixture in a pan set for hot holding and melt cheese to order on the griddle instead. Follow your local health department's requirements for hot-holding temperatures and time limits.

Scaling the batch. For 24 sandwiches, multiply everything by 3: 9 lb lamb (3 × 3 lb), 6 large onions (3 × 2), 18 cloves garlic (3 × 6), 3 Tbsp cumin, 2 Tbsp coriander (3 × 2 tsp = 6 tsp), 2 Tbsp paprika, 3 Tbsp Aleppo, 1 1/2 tsp cinnamon, 3 Tbsp kosher salt, 2 Tbsp black pepper (3 × 2 tsp = 6 tsp), 6 Tbsp tomato paste. Feta sauce becomes 2 lb 4 oz feta (3 × 12 oz = 36 oz) and 3 cups yogurt, yielding about 7 1/2 cups. Pickles become 1 lb 8 oz chilies with 3 cups vinegar, 1 1/2 cups water, 6 Tbsp sugar and 3 Tbsp salt.

Variations for the board. Swap ground beef chuck for lamb if your crowd is cautious. A vegetarian version works with finely chopped mushrooms and cooked brown lentils in place of the meat, cooked hard on the griddle so it browns rather than steams — treat it as a separate recipe to test, not a straight substitution.

Waste note. The pickle brine is worth keeping for dressings or for a second round of chilies.
