3 lbs. skirt steak, sliced very thinly
1 c. lemon juice
1 c. lime juice
12 oz. Tecate beer
Salt, pepper, garlic powder, oregano
1 lg. sliced onion

Wash meat and towel dry. Layer into a large marinade dish by adding a small amount of liquid, a layer of meat lightly seasoned with salt, pepper, garlic powder and oregano, a few circles of onion. Continue to layer until all 3 pounds of meat are in marinade.

Refrigerate for 12 hours, then "restack" the layers to ensure a fresh circulation of marinade juices. Refrigerate for another 12 hours. Barbecue or broil for a brief time and serve with fresh salsa and tortillas. Serves 6.
