Preheat your grill to medium-high heat and your oven to 425°F.
Season the chicken breast lightly with salt, pepper, and your favorite dried herbs.
Grill the chicken for about 5-6 minutes per side, or until fully cooked and juices run clear.
Meanwhile, chop a variety of vegetables such as bell peppers, zucchini, and red onion into bite-sized pieces.
Toss the vegetables with olive oil, a pinch of salt, and pepper, then spread them out on a baking sheet.
Roast the veggies in the oven for 15-20 minutes, stirring halfway through, until they are tender and slightly caramelized.
Prepare quinoa as per package instructions; for a quicker version, use pre-cooked quinoa and warm it up gently.
To plate, slice the grilled chicken breast and serve it atop a bed of quinoa, arranged alongside the roasted veggies.
Add a small side serving of nonfat Greek yogurt to bring a creamy, tangy contrast to the dish.
Enjoy your balanced, nutrient-packed lunch!
