Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper or lightly grease it.
In a shallow bowl, combine the grated Parmesan cheese, Panko breadcrumbs, garlic powder, onion powder, Italian seasoning, salt, and pepper. Mix well and set aside.
In another bowl, whisk together the egg and milk. Dip each chicken breast into the egg mixture, allowing any excess to drip off. Then, dredge the chicken in the Parmesan-Panko mixture, pressing down gently to ensure the coating adheres well.
Place the coated chicken breasts on the prepared baking sheet. Bake in the preheated oven for 25-30 minutes until golden brown and reaching an internal temperature of 165°F (75°C). Flip halfway through cooking.
While the chicken is baking, heat olive oil in a large skillet over medium heat. Add the minced garlic and sauté for about 30 seconds until fragrant. Add the fresh spinach and toss until wilted. Season with salt, pepper, and a squeeze of lemon juice. Remove from heat.
In serving bowls, start with a base of quinoa or rice. Slice the crispy Parmesan chicken and place it on top. Add a generous portion of sautéed spinach. Optionally layer on halved cherry tomatoes and avocado slices. Finish with a sprinkle of additional grated Parmesan cheese.
Serve the bowls warm and enjoy.
