Pre-heat oven to 400 degrees. Prepare baking sheet by spraying with non-stick spray.
Cut large sweet potato into quarter-sized pieces, making sure they aren’t too large (otherwise they won’t cook properly).
Place broccoli florets and sweet potato pieces in a mixing bowl and add 2 to 3 tablespoons of pesto. Mix to coat.
Spread out evenly on baking sheet, leaving just enough room for 2 chicken breasts.
Place 2 chicken breasts on baking sheet and generously spread pesto over each chicken breast, entirely coating each.
Place baking sheet in pre-heated oven and bake for 35 to 40 minutes, or until the internal temperature of the chicken breasts reaches 165 degrees.
