Homemade Macaroni-Philly Cheesesteak Style

A yummy version of homemade macaroni can be made using provolone cheese instead of cheddar. Saute a chopped onion in a little olive oil until carmalized. Add chopped deli-sliced roast beef and heat through. Mix with cooked macaroni (or other pasta) and a white sauce that has provolone melted into it. Season with salt, pepper and parsley.
