- 1 lb thinly sliced roast beef
- 2 large onions thinly sliced
- 2 tablespoons olive oil
- 1 tablespoon butter
- Salt and pepper to taste
- Optional toppings: sliced cheese lettuce, tomato, mayonnaise, mustard
Instructions
- Caramelize the Onions: Heat olive oil and butter in a large skillet over medium-low heat. Add the thinly sliced onions to the skillet and cook, stirring occasionally, for about 30-40 minutes, or until the onions are soft, golden brown, and caramelized. Season with salt and pepper to taste.
- Prepare the Sub Rolls: Slice the sub rolls or hoagie buns in half lengthwise, leaving one side intact to create a hinge. If desired, lightly toast the rolls in a toaster oven or under the broiler until golden brown.
- Assemble the Subs: Layer the thinly sliced roast beef and caramelized onions on the bottom half of each sub roll. Add any desired toppings such as sliced cheese, lettuce, tomato, mayonnaise, or mustard.
- Close the Subs: Close the subs by folding the top half of each roll over the fillings.
