1) To make meatballs: Combine turkey, onion, egg, cilantro, nuts, raisins, breadcrumbs, salt, pepper and cumin in a large bowl. Mix just until ingredients are combined and evenly mixed. With wet hands form the mixture into 1 to 1-1/2-inch balls. Set on a tray. Cover lightly with plastic wrap and chill until ready to sauté.

2) To make sauce: Combine yogurt, lemon juice, garlic, cumin and salt in a small bowl. Mix well. Cover and refrigerate.

3) To cook: Heat 2 tablespoons of olive oil in a heavy skillet over moderate heat, and sauté meatballs in batches, so as not to crowd them. As they begin to color, turn them regularly so that they are golden on all sides. They should be done when they are evenly browned and feel medium firm, but not hard when touched. Place on a paper towel to catch excess oil. Serve hot.
