Preheat your grill or grill pan over medium-high heat.
Pat the chicken breast dry, then lightly season with salt, pepper, and your favorite herbs.
Drizzle a portion of olive oil over the chicken to prevent sticking and enhance flavor.
Grill the chicken breast for about 6-7 minutes per side until it reaches an internal temperature of 165°F.
Preheat the oven to 400°F for the vegetables.
Wash and cube the sweet potato into bite-sized pieces. Toss with a little olive oil, salt, and pepper.
Spread the sweet potato on a baking sheet and roast in the oven for about 25-30 minutes, until tender and slightly caramelized.
Meanwhile, cut the broccoli into florets, toss with a light drizzle of olive oil, salt, and pepper.
Add the broccoli to the baking sheet during the last 10-12 minutes of sweet potato roasting, ensuring both vegetables finish cooking together.
Plate the grilled chicken alongside the roasted sweet potato and broccoli, and serve warm.
