Here’s a general guide on how to prepare Philly Cheesesteak Egg Rolls:

1. Heat some oil in a skillet over medium-high heat. Add the sliced onions (and bell peppers, if using) and sauté until they are soft and slightly caramelized. Remove them from the skillet and set aside.

2. In the same skillet, cook the thinly sliced steak until it’s browned and cooked through. Season with salt and pepper to taste. Remove the steak from the skillet and set aside.

3. Take an egg roll wrapper and place a slice of cheese in the center. Add a small amount of the cooked steak and sautéed onions (and bell peppers, if using) on top of the cheese.

4. Fold the sides of the egg roll wrapper over the filling, then roll it up tightly, sealing the edges with a bit of water.

5. Heat vegetable oil in a deep fryer or large pot to about 350°F (175°C). Carefully place the egg rolls into the hot oil, a few at a time, and fry until they are golden brown and crispy. This usually takes about 3-4 minutes.
