Divide the filling evenly between 8-10 tortillas, about 1/3 cup each. Roll tortillas and place them seam side down in the pan. Cover enchiladas with the remaining salsa and sprinkle with cheese. Cover pan with foil and bake in the preheated oven for 25-30 minutes until cheese is melted and bubbly. Sprinkle with chopped cilantro and serve with sliced avocado.
