# Ingredient List:
→ Beef
01 - 1 lb ribeye steak, thinly sliced (partially frozen for ease)
→ Vegetables
02 - 1 large yellow onion, thinly sliced
03 - 1 green bell pepper, thinly sliced (optional)
→ Cheese
04 - 8 slices provolone cheese (alternatively American cheese or Cheese Whiz)
→ Bread
05 - 4 hoagie rolls, split lengthwise
→ Condiments & Cooking
06 - 2 tablespoons vegetable oil
07 - Salt and black pepper, to taste
# How to Make:
01 - Place ribeye steak in the freezer for 30 to 45 minutes to firm up, then slice as thinly as possible against the grain.
02 - Heat 1 tablespoon of vegetable oil in a large skillet over medium heat. Add sliced onions and green bell pepper if using; cook while stirring until soft and lightly browned, approximately 5 to 7 minutes. Remove from skillet and set aside.
03 - Add remaining 1 tablespoon of oil to the skillet. Increase heat to medium-high and add beef slices in a single layer. Season with salt and black pepper. Cook, stirring occasionally, until beef is just browned, about 2 to 3 minutes.
04 - Return sautéed onions and peppers to the skillet. Stir to combine thoroughly with the beef.
05 - Divide the beef and vegetable mixture into four portions directly in the skillet. Place 2 slices of cheese atop each portion and allow to melt for about 1 minute.
06 - Split hoagie rolls lengthwise, leaving one side connected. Toast lightly if desired.
07 - Use a spatula to lift each cheesy beef portion and transfer into individual hoagie rolls. Serve immediately.
