Preheat the oven to 350°F.
Spray a sheet pan with a light coating of non stick spray.
Shred the rotisserie chicken. Add to a bowl and toss with the taco seasoning, salt and pepper.
1 rotisserie chicken, shredded (~3-4 cups shredded is plenty), 1 Tbsp. taco seasoning, 1/2 tsp. salt, 1/2 tsp. pepper
Start to build and layer the nachos on the sheet pan: add a layer of half the bag of chips, half of the chicken, half of the beans, and half of the cheese.
1, 12 oz. bag corn tortilla chips (try to look for thick chips as opposed to thin chips), 1, 15.5 oz. can pinto beans, drained and rinsed, 1, 15 oz. can black beans, drained and rinsed, 16 oz. cheese (Monterey jack, cheddar, Colby), or more as needed!
Repeat these layers one more time with the remaining ingredients with the cheese as the final layer on top.
Bake for 10 minutes or until everything is warmed through and the cheese is nice and melty.
Add all of your favorite toppings and dig in immediately!
