Preheat your grill or grill pan over medium-high heat.
Season the 3 oz chicken breast lightly with salt, pepper, and any preferred herbs.
Grill the chicken for about 6-7 minutes per side, or until the internal temperature reaches 165°F.
Meanwhile, preheat your oven to 425°F for roasting broccoli.
Toss 1 cup of broccoli with 2 teaspoons of olive oil, salt, and pepper, and spread evenly on a baking sheet.
Roast the broccoli in the oven for about 15-20 minutes until tender and slightly crispy on the edges.
Prepare 1/2 cup of cooked quinoa according to package instructions if not already prepared.
To serve, place the quinoa on a plate, add the grilled chicken on top, and arrange the roasted broccoli on the side.
Enjoy your balanced and nutritious lunch!
