Pat the chicken breast dry and season with a pinch of salt and pepper.
In a small bowl, combine the juice and zest of 1/2 lemon, 2 minced garlic cloves, and 1 teaspoon of olive oil.
Coat the chicken breast evenly with the lemon garlic mixture and let it marinate for at least 10 minutes.
Preheat a non-stick skillet over medium-high heat. Once hot, place the chicken breast in the skillet and sear for about 4-5 minutes per side until golden brown and cooked through.
Meanwhile, preheat the oven to 400°F. Toss the broccoli with a light drizzle of olive oil, salt, and pepper, and spread it on a baking sheet.
Roast the broccoli in the oven for 15-20 minutes until tender and slightly crispy on the edges.
Heat the brown rice if needed, or plate freshly cooked brown rice, about 1/2 cup serving.
Assemble the plate with the pan-seared chicken breast, roasted broccoli, and brown rice. Drizzle any remaining lemon garlic sauce over the chicken for extra flavor.
Serve immediately and enjoy your balanced, flavorful dinner.
