In a skillet over medium-high heat, add the ground Italian pork sausage. Cook for about 8 minutes, breaking it apart with a spatula, until browned and fully cooked.

Cut your wonton wrappers diagonally into triangles. Heat about an inch of vegetable or canola oil in another pan over medium heat and fry the wonton triangles in batches for about 2 minutes on each side until golden and crispy.

Preheat your oven to 375°F (190°C). On a baking sheet, layer the crispy wonton chips, sprinkle with shredded pepper jack cheese, sausage crumbles, pepperoni slices, and top with mozzarella cheese.

Bake for about 5 minutes, or until the cheese is bubbly and golden.

Remove the nachos from the oven and serve immediately with marinara sauce for dipping.
