Preheat oven to 350 degrees.
Prepare Jalapeño Cream Sauce according to instructions and set aside.
Heat olive oil in a large pan over medium-high heat. Add onions, bell peppers, corn, jalapeño, cumin, chili powder, salt and pepper to the pan and lower heat to medium. Cook, stirring frequently, until veggies have begun to brown and are slightly softened (approx. 5-7 minutes). Remove veggies from heat and add half of the jalapeño cream sauce to the pan and stir to combine.
Add refried beans to a bowl with 2 tablespoons of water and stir to combine.*
To assemble, spread 1/2 cup enchilada sauce on the bottom of a baking dish. Layer 4 tortillas on top of the enchilada sauce, followed by half of the refried beans, half of the black beans and half of the veggies. Repeat layers, beginning with 1/2 cup of enchilada sauce. To finish it off, layer the 4 remaining tortillas on top, followed by the final 1/2 cup of enchilada sauce. Place in the oven and cook for 25 minutes, uncovered.
Increase oven heat to broil and cook for an additional 5 minutes, or until top begins to brown. Remove from oven and allow to cool for 10-15 minutes.
Top casserole with jalapeño slices, remaining jalapeño cream sauce and cilantro. Slice and serve.
*This makes them easier to spread.
**If you plan on freezing for later: assemble casserole per instructions but do not bake. Allow to cool completely before covering and placing in the freezer. When ready to cook, add 45-60 minutes onto the normal cooking time.
