Preheat the oven to 400°F. Rinse and drain the chickpeas, then pat them dry with a paper towel.
Toss the chickpeas with a pinch of salt, pepper, and a tiny drizzle of olive oil. Spread them out on a baking sheet and roast for 20-25 minutes until crispy, stirring halfway through.
While the chickpeas roast, season the chicken breast with salt, pepper, and a sprinkle of the fresh herbs. Grill or pan-sear the chicken over medium heat until fully cooked, about 5-7 minutes per side.
Allow the chicken to rest briefly, then slice it into strips.
In a large bowl, combine the mixed greens, halved cherry tomatoes, sliced cucumber, and minced red onion.
Whisk together the lemon juice, remaining olive oil, and chopped fresh herbs to create the dressing.
Add the sliced chicken and roasted chickpeas to the salad bowl, drizzle the dressing over the top, and gently toss to combine.
Serve immediately and enjoy this vibrant, nutrient-packed meal.
