# 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, per preference)
→ Bread
05 - 4 hoagie rolls or long sandwich rolls, split
→ Condiments and Cooking
06 - 2 tbsp vegetable oil
07 - Salt, to taste
08 - Black pepper, to taste
# Directions:
01 - Place ribeye steak in the freezer for 30–45 minutes to firm up for thin slicing. Slice as thinly as possible against the grain.
02 - Heat 1 tablespoon of oil in a large skillet over medium heat. Add the sliced onions and, if using, bell peppers. Cook while stirring until soft and lightly browned, about 5 to 7 minutes. Remove vegetables to a plate.
03 - Add remaining oil to the skillet and increase heat to medium-high. Lay sliced beef in a single layer, season with salt and black pepper, and cook, stirring occasionally, until just browned, about 2 to 3 minutes.
04 - Return sautéed onions and bell peppers to the skillet and stir to evenly combine with beef.
05 - Divide the beef and vegetable mixture into four equal portions in the pan. Place two slices of cheese atop 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 transfer it into a hoagie roll. Serve immediately.
