# What You Need:
→ Beef
01 - 1 pound 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 tablespoons 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 it up, then slice as thinly as possible against the grain.
02 - Heat 1 tablespoon of oil in a large skillet over medium heat. Add the onions and bell peppers if using, and cook, stirring occasionally, until softened and lightly browned, about 5 to 7 minutes. Remove from skillet and keep warm.
03 - Add the remaining tablespoon of oil to the skillet and increase heat to medium-high. Add the sliced beef in a single layer, season with salt and pepper, and cook, stirring occasionally, until just browned, about 2 to 3 minutes.
04 - Return the sautéed onions and bell peppers to the skillet with the beef and stir to combine evenly.
05 - Divide the beef and vegetable mixture into four equal portions in the skillet. Place 2 slices of cheese over each portion and let melt, approximately 1 minute.
06 - Split the hoagie rolls lengthwise, keeping one side intact. Toast lightly if desired.
07 - Use a spatula to lift each cheesy beef portion from the skillet and place it into a prepared roll. Serve immediately.
