I am so glad I am not the only one looking for these. I can get penne, shells, and the cork screw shaped pastas, and of course spaghetti, and I finally found small elbow macaroni, but nowhere have I seen anything that approximates the flat pasta with the curled edges that you'd use for tuna casseroles and Hamburger helper. My family sends me the sauce packs for Hamburger/Tuna helper and I just use rice or pasta from here, it'd be nice to have the flat pasta instead of using the corkscrew stuff.
Tip - instead of sending boxes of Kraft M+C and the aforementioned Hamburger Helper or any other boxed stuff from home, have the sender just send the packets, along with the part of the box with the instructions. It saves on weight and space for posting.
