4 chicken breast halves, skinned and boned
1 lg. onion, sliced
1/4 c. soy sauce
1 tsp. Worcestershire sauce
1 tbsp. vegetable oil
1 tsp. ground cumin
Tortillas
Guacamole
Sour cream
Cheddar cheese
Lettuce
Tomatoes, sliced
Salsa

Marinate chicken and onion in marinade of soy sauce, Worcestershire sauce, oil, and cumin for 1 hour. Grill for about 4 minutes on each side. (Place onions to outside as they will not need as much cooking time.) Brush with marinade before and after turning. Cut chicken into thin strips and separate onion into rings. Fold into warm tortillas and top with guacamole, sour cream, grated Cheddar cheese, lettuce, tomato and salsa.
