1 medium onion, grated

1/3 cup chopped fresh parsley

2 teaspoons ground cumin

1 teaspoon salt

1/2 teaspoon freshly ground pepper

Olive oil for cooking kefta

6 pita breads

Tahini Dressing (recipe follows)

For the kefta, place all the ingredients in a mixing bowl and knead with your hands until blended. Shape into 12 oval patties.

Heat the grill or broiler. Brush the kefta with oil and grill or broil 3 to 4 minutes each side. Or heat 3 tablespoons oil in a cast-iron pan over high heat and saute the kefta 3 minutes each side.

Meanwhile wrap the pitas in foil and warm in oven.

To serve, cut the pitas crosswise in half. Fill each with lettuce, tomato slice and one kefta patty. Spoon over some of the tahini dressing.
