  • Oil – We use extra-virgin olive oil for this recipe.
  • Aromatics – Use either yellow or red onion.
  • Peppers – We use a mix of both green and red peppers.
  • Tomato – We use fresh rather than canned.
  • Corn – Fresh is always best, but you can use frozen or no sodium canned (drained first).
  • Pinto Beans – Use no or low sodium canned pinto beans to keep things healthy.
  • Chicken – Chicken breasts work best for this recipe, but you can use thighs or even sliced rotisserie chicken if you’re short on time.
  • Chicken Broth – Just a little chicken broth added to the mix helps to blend the flavors.
  • Lime Juice – This adds a nice pop of fresh flavor.
  • Cilantro – Adds a lot of flavor.
  • Tortillas – We usually serve this casserole with warm corn tortillas, but flour works well too. Or serve it in a bowl over rice instead.
  • Garnish – Serve with lots of avocado slices, sour cream, pico, salsa, lime wedges, Pickled Jalapeno and Pickled Radish
