# What You Need:
→ 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 as preferred)
→ Bread
05 - 4 hoagie rolls or long sandwich rolls, split
→ Condiments & Cooking
06 - 2 tbsp vegetable oil
07 - Salt, to taste
08 - Black pepper, to taste
# Step-by-Step Guide:
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 bell peppers if using; cook, stirring occasionally, 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. Place sliced beef in a single layer, season with salt and black pepper, and cook, stirring occasionally, until just browned, approximately 2 to 3 minutes.
04 - Return sautéed onions and peppers to the skillet with beef. Stir to combine evenly.
05 - Divide mixture into four portions within the skillet. Lay 2 slices of cheese over each portion and allow to melt for about 1 minute.
06 - Split hoagie rolls lengthwise, leaving one side attached. Optionally toast lightly for added texture.
07 - Using a spatula, transfer each cheesy beef portion into a prepared roll. Serve immediately while hot.
