Preheat your grill or grill pan over medium-high heat.
Season the chicken breast lightly with salt and pepper.
Grill the chicken for approximately 6-7 minutes on each side or until fully cooked and the internal temperature reaches 165°F.
While the chicken is grilling, prepare the salad by dicing the cucumber, halving the cherry tomatoes, slicing the red bell pepper, and finely chopping the red onion and fresh parsley.
In a large bowl, combine the chickpeas, diced vegetables, and parsley.
In a small bowl, whisk together olive oil, lemon juice, salt, and pepper to create the dressing.
Drizzle the dressing over the salad and toss gently to combine.
Dice the avocado just before serving and gently fold it into the salad to keep its shape and creaminess.
Slice the grilled chicken breast and serve it alongside or atop the crunchy chickpea salad for a balanced, flavorful lunch.
