Preheat your oven to 400°F.
Prepare the chicken by pounding the 4 oz chicken breast to an even thickness.
In a shallow bowl, mix the breadcrumbs with a pinch of salt, pepper, and any desired Italian herbs.
Lightly beat the half egg in another bowl.
Dip the chicken into the beaten egg, then coat thoroughly with the breadcrumb mixture.
Place the breaded chicken on a baking sheet lined with parchment paper.
Bake the chicken in the oven for about 20 minutes, or until it is cooked through and the coating is golden and crispy.
While the chicken bakes, toss the asparagus spears in 1 teaspoon of olive oil, season with a little salt and pepper, and arrange them on a separate baking sheet.
Roast the asparagus in the oven for about 10-12 minutes until tender.
About 5 minutes before the chicken is done, remove the chicken from the oven and spoon 1/2 cup marinara sauce over the top. Sprinkle 1 oz of mozzarella and 1 tbsp Parmesan cheese on top.
Return the chicken to the oven to melt the cheese, about 5 minutes.
Plate the chicken alongside the roasted asparagus and enjoy your balanced, nutritious meal.
