baked sweet potato fries

When looking for a place to go, I always choose the one (if there is one) that serves sweet potato fries. That's only because I've never been able to make them taste good. Well here is a great recipe!

Ingredients:
2 large sweet potatoes (get the purple ones if available- huge difference!), sliced into fries
1/4 cup fresh parmigiano reggiano cheese block, grated
1 egg white, whisked
cooking spray
salt
pepper

Preheat oven to 425 degrees. Spray large cookie sheet with cooking spray. Dunk sweet potato fries into egg white and spread out onto cookie sheet. Sprinkle cheese over the fries. Sprinkle salt and pepper. Pop into oven for 30 minutes or until tender.
