I used some lasagna noodles from my pantry that I had price-matched for $0.79 (SCREAMING DEAL).
…and chopped them up! Voila, meat lasagna.
Note: Unfortunately, I won't be able to provide the lasagna recipe that I used. My version was FAR too adapted for it to make any sense, and I can't find the ATK lasagna recipe online so I don't feel like I should copy it from the book and share it on my own website. But the concept should work for ANY lasagna recipe! Use what you have, stock up when it's on sale, and freeze, freeze, freeze.
