Preheat the oven to 425℉.
In a bowl, toss the potatoes in cooking oil, salt, pepper and the grated parmesan. Then add then to a oiled sheet pan cut side down. Bake in the oven for 15 minutes.
While baking, oil the chicken with 2 TB oil then cover with salt and pepper. Also, toss the asparagus in oil with salt, pepper and the grated parmesan.
When the 15 minutes are up, remove the pan from the oven then add the asparagus and chicken to the pan. Mix together the breadcrumbs and parmesan with 1 TB oil then place that mixture on top of the chicken.
Place the sheet pan back in the oven and bake for 20-25 minutes or until chicken is cooked through and the breadcrumbs on top of the chicken are golden.
Remove from the oven when finished then top with a final garnishing of grated parmesan before serving.
