Preheat oven to 375°F (190°C) and lightly grease a 9x13 inch baking dish with olive oil.

In a small bowl, combine breadcrumbs, Parmesan cheese, garlic powder, oregano, salt, and pepper.

In a large bowl, beat the eggs. Add chicken pieces and toss to coat completely.

Dredge the egg-coated chicken pieces in the breadcrumb mixture, pressing gently to adhere.

In a small bowl, mix the cottage cheese or Greek yogurt with 1 cup of the mozzarella cheese.

Spread half of the marinara sauce in the bottom of the prepared baking dish.

Arrange half of the breaded chicken pieces over the sauce in a single layer.

Dollop half of the cheese mixture over the chicken.

Repeat layers with remaining marinara, chicken, and cheese mixture.

Top with remaining mozzarella cheese, spreading evenly to the edges.

Bake uncovered for 30-35 minutes, or until the chicken reaches 165°F internal temperature and the cheese is bubbly with golden-brown spots on top.

Let cool for 5-10 minutes before serving. Garnish with fresh basil or parsley if desired.
