Preheat the oven to 400°F

Place chicken on a prepared baking sheet.

Combine the olive oil, balsamic vinegar, orange juice, and zest.

Drizzle the olive oil mixture over the chicken breast.

If adding veggies, toss veggies with 1 tsp of oil, salt, and pepper to taste and place around the chicken.

Bake for 20- 30 minutes until the chicken is cooked through.
