First, gather all of your ingredients and set the oven to 350 degrees.
Next, time to cook the pasta. Cook it to firm, not too soft, since we're going to bake it.
Chop the onions, peppers, and the cilantro.
While the pasta is still cooking, shred the cheese on the smallest grate setting.
Once the pasta is done cooking, drain it and then mix everything except the cheese back in the pot.
When it's all combined, add in the cheese.
Put the enchilada pasta mix into a casserole dish and bake at 350 for 30 minutes.
When it's done, it's time to eat up!
