Take your cooled black bean and veggie filling and add 1 cup of shredded Mexican cheese to it and mix
Spread a little butter on a griddle or pan and heat up your tortilla on medium low heat. While the tortilla is on the griddle, start to add about 2 large spoonfuls of the black bean and veggie filling to the center and then slowly roll into an enchilada and lightly grill it. Do this for all your tortillas
In another large heavy bottom pan, such as a cast iron, Le Creuset, or something similar, grease with oil or non-stick cooking spray and add a light layer of the enchilada sauce
Start to place your enchilada rolls in the pan until filled, layer the top with the enchilada sauce, the remaining cheese, and top with jalapeno slices
Turn the gas on low and cover and cook for 3-5 minutes or until cheese has melted. Be careful and make sure you watch your pan so the bottom of your enchiladas don't burn, you just want them to get a slight crisp and for the cheese to melt
Garnish with fresh chopped cilantro and serve hot!
