Shrimp Fajitas

1 pound shrimp, shelled
1 cup lightly packed chopped cilantro
1 clove garlic, pressed
1/3 cup lime juice
4 to 6 flour tortillas
1 Tbsp vegetable oil
2 green bell peppers, sliced
1 onion, sliced
1/2 cup plain non-fat yogurt
green salsa (optional)

Marinate shrimp in lime juice with garlic and cilantro for 20 minutes at room temperature.

Warm tortillas in foil in oven. Heat oil in skillet and saute bell peppers and onions for 10 minutes, stirring occasionally.

Take vegetables out and put shrimp with juice in. Cook on high heat about 3 minutes until done (cut to test, should be opaque in center).

Put vegetables back in pan, warm them up, add yogurt. Place mixture on flour tortillas, roll them up, and top with salsa.
