If you're looking for a different-than-the-potato-chip-covered tuna casserole, look no further than the one I grew up with. It's almost like a strata or custard - give it a try! I've never had a better tuna casserole! It tastes even better the second day and freezes well when cut and wrapped in individual pieces. I recommend American cheese over Velveeta - tried it once and it just wasn't the same. You can use a larger can of tuna if you like.
