Instructions

1. Preheat oven to 400 F
2. If making the homemade enchilada sauce, place all ingredients in a blender and blend until smooth.
3. Make the filling: Heat oil in a large skillet over medium-high heat. Add onion and stir 2-3 minutes until fragrant. Lower heat to medium add bell pepper, yams, garlic and salt. Saute this until yams and peppers are tender about -7-9 minutes. If mixture gets dry, add a slash of water, lower heat and cover and gently steam until yams are fork tender. Fold in the fresh corn and cumin, coriander and oregano. Saute 3 more minutes. Remove from heat. Add the black beans, taste for salt, adding more if you like. Stir in half the cilantro.
4. Grease a 9 x 13 baking dish. Pour 1/2 cup of the enchilada sauce and spreading around so the bottom of the pan is nicely coated.
5. Assemble your Enchiladas: Place 1/2 cup filling down the center of the tortilla add 2-3 tablespoons grated cheese over top and wrap it up tightly. Place enchilada seam side down over the sauce. Repeat with the remaining 7 tortillas nestling them side by side. Pour the remaining Enchilada Sauce over the enchiladas, leaving the edges exposed if you like (for crispy edges). Sprinkle with remaining cup of cheese.
6. Place in the hot oven, foiled for 20 minutes then uncover for the last 6-10 minutes until cheese is nice and melty. Let stand 10-15 minutes before serving ( tented with foil). Scatter the remaining chopped cilantro over the enchiladas. Serve with sour cream and hot sauce.
