Preheat oven to 400 F.

Drizzle 1-2T olive oil over the chicken breasts. Save the remainder for the vegetables. Sprinkle the chicken breast evenly with the following: 1/2 tsp thyme + 1/2 tsp rosemary + 1 tsp garlic powder + S&P to taste.

Peel & cut 2 large sweet potatoes and 1 head broccoli into 1" pieces.

Toss the sweet potatoes and broccoli with the following: 2T olive oil + 1/2 tsp thyme + 1/2 tsp rosemary + 1/4 tsp garlic powder + S&P to taste

Arrange the chicken, sweet potato, and broccoli on a sheet pan. Make sure that the pan is not overcrowded to prevent steaming.

Roast for 25-30 minutes until chicken is cooked through to 165 F. Remove from oven and toss the veggies halfway through cooking.
