  • Corn, frozen or canned - 1 1/2 cups

  1.

Stir until spices are fragrant. Whisk in tomato paste and stock. Simmer for 5 minutes to let the flavors come together and the sauce reduce slightly. (Note: sauce will be fairly thin.)

  1. Heat oven to 400F / 204C degrees.

  2. Spray a square baker with nonstick cooking spray. (Note: This is for 4 servings. If making 2 servings, you can assemble this in a loaf pan; if making 8 servings, use a large rectangular baker.)

  3. Heat a large skillet or saute pan with the first portion of cooking oil (portion for casserole) over medium heat. Add zucchini, bell peppers, and white parts of green onions with some salt. Saute until the zucchini is tender, 6 to 8 minutes. Season the vegetables with some salt. Transfer the vegetables to a bowl and return the pan to heat.

  4. To the heated pan, add the second portion of cooking oil. Add in chicken and cook, breaking the chicken apart until cooked through, 6 to 8 minutes. Season it with some salt and pepper as it cooks.

  5. Pour enchilada sauce over the chicken and bring to a simmer. Stir in the cooked vegetables and corn. Simmer everything together for 1 minute more.

  6. In the prepared baker, spread ⅓ of the chicken mixture in the bottom. Top with 1/3 the tortillas and ⅓ of the cheese. Repeat the layers, reserving the last portion of cheese. (Note: If the baker is filled nearly to the top, place it on a rimmed sheet pan to catch any spills as the dish bakes.)

  7. Cover the baker tightly with foil and bake until the casserole is heated through, ~35 minutes.

  8. Remove the foil and add the last ⅓ of the cheese. Bake for another 10 minutes until the cheese on top is bubbling and the tortillas are lightly browned.

  9. Just before serving, toss the lettuce with vinaigrette until dressed to your liking.

  10. Slice the casserole and serve with green parts of green onions on top and sour cream. Enjoy salad on the side.
