I buy "SteakEze Thinly Sliced and Shaped Sirloin Steak Strips" in the frozen aisle at "Sam's Club" to make these. So quick and easy. A family favorite.
4 (6-inch) sub rolls, partially split open
1 tablespoon olive oil
salt and pepper
8 ounces white mushrooms, trimmed and sliced thin
1 onion, sliced thin
1 red bell pepper, stemmed, seeded, and sliced thin
1 tablespoon A1 steak sauce
1 teaspoon minced fresh oregano or 1/4 teaspoon dried (I prefer 1/4 tsp of 'Italian Seasoning' instead, but oregano is good, too)
8 slices deli Provolone cheese
Position oven rack 8 inches from broiler element and heat broiler. Line baking sheet with aluminum foil. Open rolls partially, arrange cut side up on prepared baking sheet, and broil until lightly toasted, about 2 minutes. Do not turn broiler off. (Note: sometimes I will brush the insides of the rolls with a little melted butter before broiling, just to add some additional flavor).
Cook purchased steak strips in a skillet according to directions on box. Move to a plate when cooked.
Add remaining 1 tablespoon oil, mushrooms, onion, bell pepper, and 1/2 teaspoon salt to now-empty skillet and cook until vegetables are softened and lightly brown, about 8 minutes. Stir in sliced steak, steak sauce, and oregano and cook until beef is no longer pink.
Divide steak mixture among rolls and top with provolone. Broil sandwiches until cheese is melted and spotty brown, about 5 minutes. Serve.
