Heat a large, heavy sauté pan over medium-high heat and brown the sausage, breaking up any large clumps with a spatula.
When the sausage is browned and cooked through, add the onions, peppers, and tomatoes, stirring occasionally.
While the sausage mixture is cooking, combine the pickled jalapeño and pizza sauce and reserve.
When the vegetables have softened, whisk the eggs together thoroughly and add to the sausage and vegetable mixture, scrambling until the eggs reach their desired consistency. Remove from heat when done.
On a griddle or in the microwave, heat the tortillas.
Evenly distribute the sausage and egg mixture over the 6 tortillas, top with the desired amount of mozzarella cheese and pizza sauce, and garnish with chopped cilantro. Fold and serve.
