Follow these steps to create your delicious Philly Cheesesteak Egg Rolls:

1. Prepare the Meat: Heat olive oil in a skillet over medium heat. Add the thinly sliced steak, seasoning with salt, pepper, and garlic powder. Cook until browned, about 5-7 minutes.

2. Sauté the Veggies: Stir in the chopped onion and bell pepper (if using). Sauté for an additional 5 minutes until the veggies are tender.

3. Add the Cheese: Remove the skillet from heat and stir in the shredded provolone cheese until melted and combined with the meat and veggies.

4. Get the Egg Rolls Ready: Lay an egg roll wrapper on a clean surface, positioning it in a diamond shape (point facing you).

5. Fill the Wrapper: Spoon 2 tablespoons of the cheesesteak mixture into the center of the wrapper.

6. Roll the Egg Roll: Fold the bottom point over the filling, then fold in the sides. Roll it up tightly, sealing the top corner with a bit of water.

7. Heat the Oil: In a large pot or deep fryer, heat oil over medium-high heat until it reaches about 350°F (175°C).

8. Fry the Egg Rolls: Carefully place a few egg rolls in the hot oil, frying until golden brown, about 3-4 minutes per side. Do not overcrowd the pan.

9. Drain Excess Oil: Once cooked, transfer the egg rolls to a paper towel-lined plate to drain excess oil.

10. Serve Warm: Let them cool slightly before serving. Pair with hot sauce or your favorite dipping sauce for extra flavor.
