Preheat your grill to medium-high heat and set the oven to 400°F for roasting the vegetables.
Season the 4.5 oz chicken breast lightly with salt, pepper, and any herbs of choice.
Place the chicken on the grill and cook for about 6-7 minutes per side until grill marks appear and the internal temperature reaches 165°F.
Meanwhile, dice the 1/2 medium sweet potato into cubes and toss with olive oil, salt, and pepper. Spread them out on a baking sheet.
Roast the sweet potato in the oven for 20-25 minutes, stirring halfway through, until tender and slightly caramelized.
At the same time, lightly toss 1 cup of broccoli with a little olive oil, salt, and pepper, and add to the baking sheet during the last 15 minutes of roasting.
Once everything is cooked, plate the grilled chicken alongside the roasted sweet potato cubes and broccoli. Drizzle any remaining olive oil over the dish if desired.
Serve warm and enjoy your balanced, nutrient-packed lunch.
