Preheat the oven to 400 degrees F.Pour ¼ of the enchilada sauce in the bottom of of a 9x13" pan.Divide the chicken and the red bell peppers evenly between the 8 tortillas (about ½ cup of chicken per tortilla). Add 1-2 tablespoons of cheese to each tortilla, pour about 1 tablespoon of enchilada sauce in each tortilla, then roll up and place in the pan (making sure that the seam of each tortilla is face-down in the pan so that they don't come unrolled).Pour the remaining enchilada sauce on top of the rolled tortillas and top with the remaining cheese.Bake for 15-20 minutes or until the cheese starts to bubble. Let sit for a couple of minutes before serving.
