Ingredients
  

Protein

  • 2 lbs boneless, skinless chicken breasts, cubed

Veggies

  • 2 medium zucchinis, sliced
  • 1 each red bell pepper, diced
  • 1 each yellow bell pepper, diced

Sauce

  • 1 cup marinara sauce

Spices & Oil

  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1 tsp dried oregano
  • 1 tsp dried basil
  • 1/2 tsp salt
  • 1/2 tsp black pepper
  • 2 tbsp olive oil divided

Toppings

  • 1 cup mozzarella cheese, shredded
  • 1/2 cup parmesan cheese, grated

Instructions
 

Preparation

  • Preheat your oven to 375°F (190°C).
  • In a large skillet, heat 1 tablespoon of olive oil over medium heat.
  • Add the cubed chicken breasts to the skillet and cook until browned on all sides, about 5–7 minutes; remove from heat.
  • In a large mixing bowl, combine the sliced zucchinis, diced red and yellow bell peppers, garlic powder, onion powder, oregano, basil, salt, and pepper; drizzle with the remaining olive oil and toss to coat.

Baking

  • In a baking dish, arrange half of the vegetable mixture on the bottom, then layer the browned chicken over the vegetables and spread the marinara sauce over the chicken.
  • Add the remaining vegetable mixture on top of the chicken and sauce, then sprinkle the shredded mozzarella and grated parmesan evenly over everything.
  • Cover the baking dish with foil and bake in the preheated oven for 20 minutes.
  • Remove the foil and continue to bake for another 10–15 minutes, until the cheese is golden and bubbly; let cool for 5 minutes before serving.

Notes

Serve over a scoop of cooked rice or creamy polenta for extra comfort. Pair with a crisp green salad and a lemon vinaigrette to brighten the plate. Add crusty bread or garlic bread for dipping in the cheesy sauce.
