Preheat your grill to medium-high heat.
Season the chicken breast with your preferred spices, such as a pinch of salt, pepper, and garlic powder.
Grill the chicken breast for about 6-7 minutes on each side until fully cooked and the internal temperature reaches 165°F.
While the chicken is grilling, rinse 1/4 cup of dry quinoa under cold water. Combine it with 1/2 cup water in a small pot and bring it to a boil.
Once boiling, reduce heat to a simmer, cover, and let it cook for 15 minutes until the water is fully absorbed and the quinoa is fluffy.
Preheat your oven to 425°F for roasting the broccoli.
Toss the broccoli with a light spray of cooking oil, a pinch of salt, and pepper. Spread it on a baking sheet in a single layer.
Roast the broccoli in the oven for about 12-15 minutes until tender and slightly crispy on the edges.
Plate the grilled chicken breast alongside the cooked quinoa and roasted broccoli. Enjoy your balanced and nutritious lunch!
