Pat the chicken breasts dry with a paper towel and gently pound them to an even thickness.
In a shallow dish, mix the whole wheat breadcrumbs, Parmesan cheese, Italian seasoning, garlic powder, salt, and black pepper.
Dip each chicken breast into the beaten eggs, allowing excess to drip off. Then coat it in the breadcrumb mixture, pressing gently to adhere.
In a large skillet, heat olive oil over medium heat. Add the diced bell pepper, zucchini, and halved cherry tomatoes. Sauté for about 5-7 minutes until they are tender. Remove from heat and set aside.
Place the breaded chicken breasts on a baking sheet lined with parchment paper. Bake in the preheated oven for about 20 minutes until golden brown and cooked through.
After 20 minutes, take the chicken out and spoon marinara sauce over each piece. Sprinkle with shredded mozzarella cheese. Return to the oven and bake for an additional 5-7 minutes, or until the cheese is melted and bubbly.
On each plate, place a portion of the sautéed vegetables next to the chicken. Garnish with fresh basil leaves for added flavor and color.
Notes
Use low sodium marinara sauce for a healthier option.
