Easy Cheese Steak Sandwiches

Serves 4. 

1 medium onion, sliced thinly

1 tablespoon sugar

1 lb lean flank steak, thinly sliced (easiest to slice when semi-frozen)

2-4 teaspoons Worcestershire sauce, to taste

Salt and pepper to taste

4 medium rolls (a crustier French bread/Kaiser roll works well, but can use a whole wheat roll too)

4 slices provolone

Preheat oven to 350 degrees F. Coat large, nonstick skillet with olive oil and set pan over medium high heat. When pan is hot, add onion and sugar. Sauté until the onions are tender, golden, and caramelized, about 10-15 minutes. Remove onions from pan and set aside.

Add steak to skillet and sauté until browned and nearly cooked, about 2-3 minutes per side. Add Worcestershire sauce, salt, and pepper, and cook until liquid is about absorbed.

Slice rolls in half. Divide steak evenly between rolls and top with onions and cheese. Wrap in foil and transfer to oven. Bake until cheese melts, about 10 minutes.
