Preheat your oven to 425°F for the broccoli.
Toss the broccoli with a small drizzle of olive oil, salt, and black pepper, and spread evenly on a baking sheet.
Roast the broccoli in the preheated oven for 15-20 minutes until tender and slightly crispy on the edges.
While the broccoli roasts, pat the chicken breast dry and season both sides with salt and pepper.
Heat a non-stick skillet over medium-high heat and add the teaspoon of olive oil.
Mince the garlic and add it to the skillet, allowing it to infuse the oil for about 30 seconds.
Place the chicken breast in the skillet and cook for approximately 5-6 minutes on each side until it reaches an internal temperature of 165°F.
In the last minute of cooking, drizzle the lemon juice over the chicken to incorporate its bright flavor.
Remove the chicken from the skillet and let it rest for a few minutes before slicing.
Serve the sliced chicken breast alongside the roasted broccoli and enjoy your balanced meal.
