Made this for Spring PAC 2013 and I added fresh garlic, some green onions, and I did use the half-n-half and mixed the cheddar cheese into the mixture. Thank you for posting.
A simple recipe, but nice. I added fresh ground pepper, garlic and italian seasoning. I also used penne instead of spaghetti. Next time I would mix the cheddar into the mix instead of on top. I would recommend half and half over milk.
