Preparation

Position a rack in the bottom third of the oven and preheat the oven to 350° F. Use nonstick cooking spray to lightly coat a 13 × 9-inch pan and a piece of foil large enough to cover the pan. Set aside. Filling Stir the filling ingredients together in a medium bowl, adding the 1/2 cup of cheese. Microwave a stack of 6 tortillas between damp paper towels on high power until the tortillas are hot and soft enough to roll, about 1 minute. Cover with a cloth towel to keep warm. Remove 1 tortilla at a time, keeping the other tortillas covered, and place a rounded 1/3 cup of filling down the center. Roll into a cylinder and place, seam side down, in the prepared pan. Repeat with the remaining tortillas, placing them close enough to touch. Microwave and fill the remaining 6 tortillas. Cover the pan with the prepared foil and bake for 15 minutes. Remove the foil, spread the salsa over the top, and sprinkle with cheese, as desired. Bake loosely covered, until the enchiladas are hot and the sauce is bubbly, about 20 minutes.
