Step 1: Prepare the Steak Filling

1. Sauté the Vegetables – In a large skillet, heat the olive oil over medium heat. Add the onions and bell peppers, cooking until they’re soft and caramelized, about 8-10 minutes. Transfer them to a bowl and set aside.
2. Cook the Steak – In the same skillet, melt the butter over medium-high heat. Add the sliced steak, seasoning with salt and pepper to taste. Cook for about 3-5 minutes, until the steak is browned and cooked through. Remove from heat and combine with the sautéed vegetables.

Step 2: Add Cheese to the Filling

1. Add the Cheese – While the steak mixture is still warm, add the shredded provolone cheese. Stir until the cheese melts into the filling, creating a cheesy, savory mixture. Set aside to cool slightly.

Step 3: Assemble the Egg Rolls

1. Lay Out the Wrappers – Place an egg roll wrapper on a clean, dry surface with one corner pointing toward you (like a diamond shape).
2. Add the Filling – Spoon 2–3 tablespoons of the steak mixture onto the center of the wrapper.
3. Fold the Wrapper – Fold the bottom corner up over the filling, then fold in the sides. Roll tightly toward the top corner, brushing a little water on the edge to seal it closed.
4. Repeat – Continue with the remaining wrappers and filling, placing assembled egg rolls on a plate.

Step 4: Fry the Egg Rolls

1. Heat the Oil – In a deep frying pan or pot, heat 2–3 inches of vegetable oil to 350°F (175°C).
2. Fry the Egg Rolls – Carefully add 2–3 egg rolls at a time, frying until golden brown and crispy, about 3-4 minutes per side. Remove and drain on paper towels.

Step 5: Prepare the Garlic Aioli

1. Mix the Aioli Ingredients – In a small bowl, whisk together the mayonnaise, lemon juice, garlic powder, salt, and pepper. Taste and adjust seasoning if needed.

Step 6: Serve and Garnish

1. Garnish the Egg Rolls – Place the fried egg rolls on a serving plate. Sprinkle shredded provolone cheese and chopped parsley on top for garnish.
2. Serve with Garlic Aioli – Serve the egg rolls warm with the garlic aioli dipping sauce on the side.
