Annie's Naturals has just duplicated the classic Kraft Dinner with their "blue box":
It tastes just about the same, except that you can actually get the noodles cooked so that they aren't mushy, which I can't accomplish with the Kraft original version. And you can buy a 15-pack of Annie's at Costco.
We usually have ours with kielbasa, which we call Moon Bites for our son (cut into half-circles).
