Thank everyone for the nice comments.
As for the ribs, they were the preseasoned ones from our local Costco. I've used them a few times so far, and I gotta say I like them a lot. They trim them nice, remove the membrane. It is a fantastic last minute go to if I feel like ribs.
The mac & cheese... I basically followed the recipe in the back of the macaroni box, but used around 5-6 different cheeses. Old smoked cheddar, medium cheddar, asiago, Parmesan, mozzarella, and gruyere and some other cheese I had. My son had the idea to add some prosciutto to the one pan. That was the one that disappeared.
