Homemade mac and cheese - easy as boxed
Macaroni and cheese comes in two distinct forms: the homemade, out-of-the-oven, crusty with browned cheese stuff the grownups like, and the stovetop, out-of-the-box, electric orange pasta concoction the kids like.
I submit to you a third option. Easy as the boxed stuff, pleasingly orange, and real enough to please the kid inside any grownup. My kids even eat it (I won't say prefer it, but they're happy enough).
Cook macaroni (if you can get a hold of the whole wheat kind, so much the better). When done, drain, return to the pot, and add a generous pat of butter. Once the butter melts, sprinkle in a tablespoon or so of flour. Use your fingers to sprinkle in the flour so it doesn't clump in one spot. Stir well. Add a splash of milk, and then some shredded cheese (cheddar, or a mix of cheddar and jack). Stir till everything's nicely melted. Add a little more milk if your kids like things saucy.
