Gather your ingredients for the Mediterranean Chicken Stir Fry. Chop the zucchini, red bell peppers, and red onion into bite-sized pieces, and slice the chicken breast into small cubes.

Heat a large skillet over medium-high heat and add 2 tablespoons of extra virgin olive oil. Cook the seasoned chicken pieces for 5 to 7 minutes until golden brown and no longer pink inside. Set aside.

In the same skillet, add the remaining olive oil, then the chopped red onion and minced garlic. Sauté for about 2 minutes until onions are translucent. Next, add the zucchini and red bell peppers, cooking for an additional 4 to 5 minutes.

Return the chicken to the skillet with the sautéed vegetables. Drizzle lemon juice over the mixture, gently stir to combine everything, then toss in the cherry tomatoes and crumbled feta cheese, heating for about 1 minute before serving.
