1. Preheat oven to 400 degrees. Spray a baking sheet with cooking spray.
2. Mix rice and broth together. Spread on the bottom of the baking sheet. Lay chicken breasts over the rice. Spread mini peppers on the rice, all around the chicken breasts.
3. Whisk together the olive oil, balsamic vinegar, and honey till thickened. Brush dressing over the chicken and peppers. Reserve the remaining dressing.
4. Cover and bake for 25–30 minutes. (Check that chicken is baked through before removing from the oven.) Remove baking sheet from oven and brush chicken and veggies once more with honey balsamic dressing.
