Cook's Notes:

If you're doing meat in your oven, this dish can be put in a casserole and baked at 350 degrees F for 40 minutes. Turn this into a one-dish meal by adding diced chicken, turkey, or firm tofu.

For a spicier dish, add banana peppers or finely chopped jalapeno, or use grated pepper Jack cheese.

Use green bell pepper, if you prefer. You can use just zucchini or only yellow squash, if you prefer. Substitute Monterey Jack or Parmesan cheese for the Cheddar cheese or use a combination.
