Marinate the chicken breast by combining lemon juice, freshly chopped herbs, salt, and pepper in a bowl. Coat the chicken evenly and let it sit for at least 15 minutes.
Preheat your oven to 400°F. Rinse and drain the chickpeas, then toss them with a little olive oil, lemon juice, chopped herbs, salt, and pepper.
Spread the chickpeas on a baking sheet and roast in the oven for 20-25 minutes until they turn crispy, stirring halfway through.
While the chickpeas are roasting, cook the chicken. You can either grill it on medium-high heat for about 6-7 minutes per side or bake it in the oven at 400°F for 18-20 minutes, ensuring it reaches an internal temperature of 165°F.
In a large bowl, combine the mixed greens, cherry tomatoes, cucumber, and red onion. Drizzle with a little extra olive oil and lemon juice, and season with salt and pepper.
Slice the cooked chicken breast and arrange it over the salad. Top with the crispy chickpeas for added crunch.
Serve immediately and enjoy a fresh, protein-packed meal.
