The original recipe called for ground lamb but I figured it would be just as good with ground beef which is easier for me to find. I also omitted the cinnamon and added an extra clove of garlic.
2 jarred roasted red peppers
1/3 cucumber, peeled and chopped
1/2 cup crumbled feta cheese
1/2 cup plain Greek-style yogurt
1 clove garlic
Juice of 1/2 lemon
2 pounds ground beef
1 tablespoon finely chopped onion
1 tablespoon chili powder
1 teaspoon dried oregano
1 teaspoon paprika
1 teaspoon garlic powder
2 pinches ground cinnamon
Salt and pepper
Extra-virgin olive oil (EVOO), for drizzling
4 romaine lettuce leaves
4 crusty rolls, split
Thinly sliced bell peppers, red onions, tomatoes and hot fresh chiles, for garnish
Using a food processor, puree the roasted peppers, cucumber, feta, yogurt, garlic and lemon juice.
In a large bowl, combine the lamb, onion, chili powder, oregano, paprika, garlic powder, cinnamon, 1/2 teaspoon salt and 1/4 teaspoon pepper. Form into four 4-inch patties. In a large skillet, heat a drizzle of EVOO over medium-high heat. Add the patties and cook, turning once, for 8 minutes for medium.
Place a romaine leaf and a patty on each roll bottom and top with the garnishes. Slather the sauce on the roll tops and set in place.
