Preheat the oven to 400F. Line two baking sheets with parchment paper.
Cook your brown rice according to package instructions.
In a large bowl, toss together sweet potatoes through black pepper. Divide the contents of the bowl between the two prepared baking sheets. Bake veggies for 30-40 minutes or until soft and slightly charred. Remove veggies from the oven, top with shredded cheese, then bake for another 5 minutes or until the cheese is melted.
Divide brown rice between bowls then top with cheese/veggie mixture, avocado slices, minced cilantro, a dollop of sour cream and some salsa then enjoy!
