Start by combining your chicken breasts with olive oil and preferred seasonings in a bowl. Ensure the chicken is well-coated, then cover and let it marinate in the refrigerator for at least 30 minutes, or ideally up to 4 hours.

While the chicken marinates, prepare the tzatziki sauce. Grate half a cucumber and squeeze out excess moisture. In a mixing bowl, combine the drained cucumber with Greek yogurt, minced garlic, fresh or dried dill, lemon juice, and a pinch of salt. Stir until well combined and refrigerate.

Once the chicken has marinated, heat a grill pan over medium-high heat. Add the marinated chicken breasts, cooking each side for about 5-7 minutes until they reach an internal temperature of 165°F.

Begin layering your Chicken Tzatziki Bowls by placing a generous serving of quinoa or couscous at the base. Add the sliced, cooked chicken on top, followed by a dollop of tzatziki sauce and a colorful assortment of fresh vegetables.
