In a medium-sized bowl, toss rounds with 1 tablespoon of olive oil, garlic powder, paprika, salt, and pepper until well-coated.
Lay rounds flat on a parchment-lined baking sheet and set aside.
On a second parchment-lined baking sheet, season chicken breast with olive oil, salt, and pepper, to taste. Wrap the parchment around the chicken, folding at the edges.
Bake the sweet potatoes and the chicken in the oven for 20 minutes or until the chicken is cooked through and juices run clear.
Allow both to cool. Then, shred the chicken using two forks.
Line the bottom of a medium-sized skillet with the sweet potato rounds. Top with shredded chicken, black beans, jalapeño if desired, and cheese. Broil for 5-10 minutes or until toppings are heated through and cheese is melted.
Garnish with avocado, pico de gallo, and green onion, if desired. Serve immediately.
