In a large bowl, coat chicken breasts with BBQ Sauce and Dan-O's. Mix until evenly coated.
Toss sweet potatoes + broccoli in olive oil. Season with kosher salt, black pepper, and garlic powder to taste.
Arrange chicken + vegetables onto a sheet pan in a single layer (chicken on one side, all of the broccoli together, and all of the sweet potatoes together).
Bake for 18-20 minutes, or until the internal temperature of the chicken reaches 165F and the vegetables are fork tender. Baste chicken with more BBQ Sauce + Dan-O's mixture + flip vegetables half-way through baking.
