Ingredients

1 1 lb chicken breasts (raw, sliced) or 1 lb shrimp (or a combination of the three)
1 (10 ounce) bottle teriyaki sauce
1 onion, sliced
1 green pepper, sliced
shredded lettuce
2 cups shredded cheddar cheese
flour tortilla (store bought or homemade, see below)
guacamole (optional)
sour cream (optional)

Homemade Tortillas
4 cups flour
2 teaspoons salt
1/2 cup butter, softened
1 1/2 cups water

Preparation

Mix onion, pepper, and meat in a shallow dish and cover with teriyaki sauce. Marinate for several hours.
Grill or pan fry until heated through or cooked thoroughly.
Serve with tortillas, guacamole, sour cream, and salsa.
Each person assembles their own fajitas by putting meat/vegetable mixture and topping with their choice of condiments, rolling up the tortilla and eating by hand. Be careful not to overload the tortilla.
Tortillas:
Mix all ingredients.
Form into golf ball size balls. Roll out flat into a circle.
Cook on each side in a dry non-stick pan until starting to brown. DO NOT OVERCOOK. The tortillas cook quickly and it is easy to burn them if you turn away.
