I'm throwing a party this weekend for some friends that just moved to town. Both kids (mostly 3-year-olds) and adults will be in attendance. Anyone have a tried & true kid-friendly macaroni and cheese recipe? I'd also like to serve a grown-up version of mac & cheese and was thinking about Ina Garten's Penne with Five Cheeses (Pecorino, fontina, Gorgonzola, ricotta & mozzarella). Anyone tried this before? Thanks in advance hounds!
