Preheat the oven to 400°F. Spray a rimmed baking sheet with nonstick spray and set aside.
In a large bowl, combine 2 egg whites, 1/4 cup whole wheat panko bread crumbs, 1/4 cup fat-free feta cheese (crumbled), 1/4 cup fresh parsley (chopped), 2 tablespoons fresh rosemary (chopped), and 1 pound ground chicken. Mix until evenly combined.
In a second bowl, combine 1 tablespoon olive oil, 3 cloves garlic (roughly chopped), 1/2 teaspoon kosher salt, 1 cup grape tomatoes (or cherry tomatoes), and 15 ounces chickpeas (canned, drained and rinsed). Toss to coat the tomatoes and chickpeas with the oil and garlic.
Spread the tomato and chickpea mixture in an even layer on the prepared baking sheet.
Shape the chicken mixture into 2-inch meatballs and place them on top of the tomatoes and chickpeas, spacing them evenly.
Bake for 15 to 20 minutes, or until the meatballs are firm and cooked through.
Remove from the oven and serve. Enjoy!
