In a large skillet, heat 15–30 ml vegetable oil over medium-high heat. Add chopped onion and green bell pepper, cooking for about 5 minutes until softened and starting to caramelise.

Add sliced beef to the skillet with the vegetables. Season generously with salt and pepper. Sauté, stirring often and breaking up any large pieces, until beef is fully browned and cooked through, about 5 minutes. Drain any excess liquid as needed.

Reduce heat to low. Sprinkle shredded provolone over the beef and vegetables, stirring until cheese is fully melted and distributed evenly. Remove from heat and allow the filling to cool to room temperature for easier handling.

Place an egg roll wrapper on a clean surface in a diamond orientation. Spoon approximately 30 ml of filling onto the centre. Fold the bottom corner over the filling, tuck in the side corners, and roll tightly upwards. Brush the top corner with beaten egg to seal. Repeat with remaining wrappers and filling.

Pour enough vegetable oil into a large, deep saucepan or Dutch oven to reach a depth of 5 cm. Heat over medium-high until the oil reaches 175°C. Prepare a plate lined with paper towels.
06 -
Using tongs or a slotted spoon, carefully lower 2–3 egg rolls at a time into the hot oil. Fry, turning as needed, until golden-brown and crisp on all sides, about 3–4 minutes per batch. Maintain oil temperature around 175°C throughout frying.

Transfer fried egg rolls to the prepared plate to drain excess oil. Continue frying remaining egg rolls in batches. Allow to cool briefly before serving, as the filling will be very hot. Serve warm with your favourite dipping sauce.
