Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Pound the chicken breast lightly to even thickness. Season with salt, pepper, and Italian seasoning on both sides.
Place the egg white in a shallow bowl. In another bowl, combine the whole wheat panko and grated Parmesan.
Dip the chicken breast first into the egg white, ensuring it is fully coated, then press it into the panko-Parmesan mixture to coat evenly.
Place the breaded chicken on the prepared baking sheet. Bake in the preheated oven for about 20-22 minutes, or until the chicken is cooked through and the coating turns crisp.
While the chicken bakes, prepare the asparagus: Toss it with olive oil, a pinch of salt, pepper, and a dash of Italian seasoning. Spread on a separate baking tray or arrange it around the chicken if space allows.
After the chicken has baked for about 15 minutes, remove the pan and spoon marinara sauce evenly over the chicken. Top with the part-skim mozzarella.
Return the chicken (and asparagus if on the same tray) to the oven and bake for an additional 5-7 minutes until the cheese melts and is slightly golden.
Remove from the oven, plate the chicken with a serving of roasted asparagus, and enjoy your healthy, crispy chicken parmesan!
