Start by cooking the Italian sausage in a skillet over medium heat. I like to break it up into small pieces so it cooks evenly and gets a nice golden brown color. This step adds a rich, savory foundation for the nachos.
Pour canola oil into a large pot, about a ½ inch deep, and heat to medium. Cut each egg roll wrapper into four squares. Fry a few squares at a time, flipping after 2–3 seconds for even crisping, then drain on paper towels. The wrappers turn into perfectly light and crunchy “chips.”
While the wrappers are frying, warm the alfredo sauce in a small saucepan over low heat. Stir occasionally to prevent it from sticking or separating. This creamy layer ties all the toppings together.
Place the fried wrappers on an oven-safe dish. Spoon warm alfredo sauce over the top, followed by cooked sausage, pepperonis, olives, and the Italian cheese blend. Make sure every wrapper gets a little bit of each topping for maximum flavor.
Set your oven to broil and place the dish in the oven for 30 seconds. Watch closely to ensure the cheese melts and gets slightly golden. Remove and top with fresh tomato wedges and pepperoncinis. Optional: add sliced jalapeños for extra zest.
