# What You'll 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, per preference)
→ Bread
05 - 4 hoagie rolls, split lengthwise
→ Condiments & Cooking
06 - 2 tbsp vegetable oil
07 - Salt, to taste
08 - Black pepper, to taste
# How To:
01 - Place the ribeye steak in the freezer for 30 to 45 minutes to firm up 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 the 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 the remaining 1 tablespoon of oil to the skillet and increase heat to medium-high. Add the sliced steak in a single layer, seasoning with salt and black pepper. Cook, stirring, until just browned, approximately 2 to 3 minutes.
04 - Return the sautéed onions and peppers to the skillet with the cooked beef. Stir to combine evenly.
05 - Divide the beef and vegetable mixture into four portions in the skillet. Top each portion with 2 slices of provolone cheese and cook until melted, about 1 minute.
06 - Split the hoagie rolls lengthwise, keeping one edge intact. Toast lightly if desired.
07 - Using a spatula, lift each cheesy beef portion and place it carefully inside each hoagie roll. Serve immediately.
