In a large container, combine oil, vinegar, Worcestershire sauce, thyme, salt and pepper. Stir to combine. Add steak. Coat well with the marinade. Cover and refrigerate for at least 1 hour.
Remove meat from marinade and discard marinade. Broil 4 inches from heat, or grill over medium heat 5 to 10 minutes per side or until cooked to desired doneness. Or you can also cook the steak in a non-stick skillet on the stovetop. Allow the meat to cool.
Slice the steak and place in containers or freezer bags in meal-sized portions.
Seal, label and freeze.
Thaw steak and serve on a sandwich or on top of a salad. Steak can also be warmed in the microwave or stovetop. Do not overcook if reheating.
