Combine breadcrumbs and grated cheese in one bowl and olive oil, lemon juice, and pepper in another bowl.
Preheat oven to 450°.
Lightly spray a baking dish with non-stick spray.
Dip the chicken in the lemon-oil mixture, then in the breadcrumbs to coat well.
Place each cutlet on a work surface such as a cutting board and lay 1/2 slice prosciutto, 1/2 slice cheese and a few chunks red onion on one side of the chicken cutlet.
Roll and place seam side down in a baking dish (no toothpicks needed). Repeat with the remaining chicken.
When finished, top with remaining crumbs and spray lightly with oil.
Bake 25 - 30 minutes.
Serve immediately!
Notes
Serving size is listed as one, but if you are having this as a low carb meal with a salad, I suggest you have two.Modified from Julia's Healthy Italian
