1 flank steak (1 1/2 lbs.)
1 tsp. seasoned salt, liquid smoke and bar-b-q salt
1/3 tsp. each garlic powder, black pepper
1 tsp. Accent and onion powder
1/4 c. each Worcestershire sauce, soy sauce

Trim off all possible fat. Semi-freeze meat and slice it with grain into 1/8 inch slices. Marinate overnight in a shallow glass dish with sauce made from all other ingredients. Lay strips of meat on oven rack - foil under to catch drips. Oven at 125-140 degrees for 8-12 hours. (Open door a crack if possible).
