# Required Ingredients:
→ 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, split lengthwise
→ Condiments and Cooking
06 - 2 tablespoons vegetable oil
07 - Salt, to taste
08 - Black pepper, to taste
# Directions:
01 - Freeze ribeye steak for 30 to 45 minutes to firm up. 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; cook while stirring until softened and lightly browned, about 5 to 7 minutes. Remove from skillet and set aside.
03 - Add remaining oil to the skillet and increase heat to medium-high. Add sliced beef in a single layer, season with salt and black pepper, and cook while stirring until just browned, 2 to 3 minutes.
04 - Return sautéed onions and peppers to the skillet with the beef and stir to combine evenly.
05 - Divide the beef mixture into four portions within the skillet. Place two slices of cheese over each portion and allow to melt for approximately one minute.
06 - Split hoagie rolls lengthwise, keeping one side intact. Toast lightly if desired.
07 - Use a spatula to lift each cheesy beef portion and transfer into a hoagie roll. Serve immediately.
