Step 1: Heat oven to 350 degrees. Take a 9 x 13 dish and place chicken breasts along the bottom. I leave mine whole, but if you are serving a large group of people, you could always bake ahead of time and shred to make it go a bit further.
Step 2: Top chicken with Rotel, black beans, and sliced jalapeno. Place dish in oven and bake for 45 minutes.
Step 3: Sprinkle tortilla chips, green onion, and shredded cheese over chicken and bake for an additional 15 minutes.
Serve with rice if keeping them whole, or wrap in tortillas if you shred the chicken before baking!
