Preheat your oven to 425°F and line a sheet pan with parchment paper.
In a small bowl, mix olive oil, juice from half a lemon, mixed dried herbs, garlic powder, salt, and pepper to create a marinade.
Place the chicken breast in the center of the sheet pan and brush both sides with the marinade.
Drain and rinse the chickpeas, pat them dry with a paper towel, and toss them in a little extra olive oil, salt, and pepper.
Arrange the chickpeas around the chicken on the sheet pan.
Add the broccoli florets to the pan; drizzle lightly with any remaining marinade or an extra splash of olive oil, and season with salt and pepper.
Bake in the preheated oven for 20-25 minutes until the chicken reaches an internal temperature of 165°F, the chickpeas become crispy, and the broccoli is tender and slightly charred.
Remove from the oven, plate your meal, and enjoy your nutritious, balanced dish.
