Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper.
In a small bowl, combine the juice of 1/2 lemon, olive oil, minced garlic, chopped fresh rosemary, thyme, salt, and pepper.
Place the chicken breast on a plate and brush both sides with the lemon herb mixture. Let it marinate for 10 minutes.
On the prepared baking sheet, toss the drained chickpeas with a drizzle of olive oil, a pinch of salt, and pepper.
Add the chickpeas into the oven and roast for about 20-25 minutes, stirring halfway to ensure even crisping. They should be crunchy.
While the chickpeas roast, heat a non-stick skillet over medium-high heat and add the marinated chicken breast. Cook for about 5-6 minutes on each side until crispy on the outside and the internal temperature reaches 165°F (74°C).
In the last 5 minutes of the chickpea roasting time, add the green beans (tossed lightly in olive oil, salt, and pepper) to the baking sheet to roast alongside.
Once all components are cooked, plate the chicken alongside a serving of roasted chickpeas and green beans. Drizzle any remaining lemon herb sauce over the top.
Serve warm and enjoy this balanced, flavor-packed meal!
