Gooey, meaty and melty, a Philly Cheesesteak sandwich is delicious in its simplicity. This sandwich has transcended the borders of Philadelphia to become a universal comfort food and a regular at my dinner table.
Prepare all the ingredients for the Philly Cheesesteak. The key is to slice beef into very thin slices. Cut bell peppers into long strips, onion into half rings and mushrooms into bitesize pieces.
Preheat the oiled skillet, add onions, bell peppers and mushrooms to the mixture. Cook on high heat until all veggies are golden brown. Remove from the skillet and set aside.
Add sliced beef to the same skillet, season with salt and pepper. Cook until the beef is fully cooked. Add vegetables back to the beef, toss to combine everything together. Top it off with cheese slices and let it sit for a minute to let it melt.
Fill the sandwich buns with meat mixture and serve while everything is still warm.
