L.A. (Lower Alabama) Fajitas - cooking recipe

Ingredients

1 1/2 lb. top sirloin steak
1 large yellow onion, coarsely chopped
1 large red bell pepper, coarsely chopped
1 large green bell pepper, coarsely chopped
1 Tbsp. black pepper
3 to 4 cloves fresh garlic, crushed
1 bottle (5 oz.) Lea & Perrins Worcestershire sauce
1 bottle (5 oz.) A.1. steak sauce

Preparation

In a large bowl, place steak, onion, peppers and garlic.
Set aside.
In a small bowl mix 1/2 bottle of steak sauce with 1/2 bottle of Worcestershire.
Add black pepper and stir well.
Pour this mixture over steak and vegetables, tossing to coat evenly; let marinate at least 1 hour, the longer the better.
Drain marinade back into smaller bowl, adding the remainder of the steak sauce and mix well.
Place steak on grill, turning and basting frequently until done (medium to medium-rare is best).
In a skillet, place drained marinated vegetables and a small amount of the marinade; saute until tender.
Cut steak in thin strips (against grain).
Any marinade remaining can be poured over steak strips.
