Instructions

Preheat the oven to 375°F.
In a separate bowl, mix together the RO-TEL, chili powder, and salt.
1 can (10 oz.) RO-TEL, 1 tsp. chili powder, 1 tsp. table salt
Heat 1 tablespoon of oil in a skillet over medium-high heat. Cook the onion and bell peppers until tender, about 8 minutes. Remove from the skillet and set aside.

Notes

Chicken: You can use chicken breast or chicken thighs in this recipe.

Skillet: I love making this in a cast iron skillet because it keeps it warm while it's waiting to be served, but any ovenproof skillet works. If you don't have an oven safe skillet, arrange the final ingredients in a 9x13 baking dish, which is closest to the area a 12" skillet.

Seasonings: Add any and all spices you like, ground cumin is a good one to add if you like that flavor.
