My mom used to make stuff she called can-can casserole, which included one can of cream of mushroom soup and one can of tomato soup (hence can-can) plus a mess of macaroni. That was kind of weird. manintheboat posts sometimes about a dish variously called Chili Mac, American Chop Suey, Johnny Smart, and in the Coolio Cookbook I recently was given ('gifted' seems apropos here) "Chili Mac Pimpin'". It has more actual tomato in it than can-can, but the idea is similar: a good way to shovel carbs into children.
