Ingredients

1/2 English cucumber, peeled, and grated (3/4 cup)

1/2 cup plain yogurt, preferably whole milk yogurt

2 teaspoons fresh lemon juice

2 teaspoons chopped fresh mint

1 small garlic clove, minced

Salt and pepper

1 1/2 pounds ground lamb

1/2 small onion, minced (1/4 cup)

1/4 cup chopped fresh parsley

2 teaspoons chopped fresh oregano, or 1 teaspoon dried

Salt and pepper

4 pieces pita bread (6 inches each)

2 medium beefsteak tomatoes, sliced, for serving

Preparation

Heat grill or grill pan to high. Make tzatziki: In a medium bowl, combine cucumber, yogurt, lemon juice, mint and garlic; season with salt and pepper. Cover, and refrigerate until ready to use.

Make burgers: In a medium bowl, use a fork to gently combine lamb, onion, parsley, and oregano; season with salt and pepper. Gently form mixture into 16 small patties, about 3/4 inch thick. Grill until medium-rare, 2 to 3 minutes per side.

To serve, warm pitas on the grill or directly over a gas burner, turning occasionally. Halve pitas, and fill with burgers, tomato, and tzatziki.
