Step 1 – Prepare the Steak: Place the ribeye steak in the freezer for about 20 minutes so it becomes easier to slice. Slice the steak in very thin stripes.
Step 2 – Slice the Vegetables: Cut the onions, bell peppers, mushrooms, and jalapeños into thin slices.
Step 3 – Cook the Vegetables: Heat one tablespoon of butter or oil in a skillet. Add the vegetables and cook for about 4–5 minutes until they soften and become slightly golden.
Step 4 – Cook the Steak: Add some oil to the skillet. Cook the steak strips on high heat for 2–3 minutes, seasoning with salt and pepper.
Step 5 – Combine Everything: Combine everything, cooked veggies and steak in the skillet.
Step 6 – Melt the Cheese: Place cheese slices over the steak mixture and allow them to melt.
Step 7 – Toast the Bread: Slice the hoagie rolls and lightly toast them with butter.
Step 8 – Assemble the Sandwich: Fill the toasted bread with the cheesy steak mixture and allow a small amount of cooking juices to drizzle into the bread.
Step 9 – Serve and Enjoy: Serve the sandwich hot with fries, chips, or your favorite side.
