# Ingredients List:
→ Beef
01 - 1 lb ribeye steak, thinly sliced (partially frozen for easier slicing)
→ Vegetables
02 - 1 large yellow onion, thinly sliced
03 - 1 green bell pepper, thinly sliced (optional)
→ Cheese
04 - 8 slices provolone cheese (or American cheese or Cheese Whiz, per preference)
→ Bread
05 - 4 hoagie rolls or long sandwich rolls, split
→ Condiments & Cooking
06 - 2 tbsp vegetable oil
07 - Salt and black pepper, to taste
# Directions:
01 - Place ribeye steak in the freezer for 30 to 45 minutes for easier slicing, 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 bell peppers, if using, and cook while stirring until soft and lightly browned, about 5 to 7 minutes. Transfer to a plate.
03 - Add remaining oil to the skillet, increase heat to medium-high, then add sliced beef in a single layer. Season with salt and pepper and cook, stirring, until just browned, about 2 to 3 minutes.
04 - Return onions and peppers to the skillet and stir to combine with the beef.
05 - Divide the mixture evenly into four portions in the pan. Place 2 slices of cheese over each portion and allow to melt, approximately 1 minute.
06 - Split hoagie rolls lengthwise, keeping one side intact. Toast lightly if desired.
07 - Using a spatula, lift each cheesy beef portion and place it into a roll. Serve immediately.
