Anyway, just about everyone has their own version of tater tot casserole. I started making this back when Rock and I were first married and it has evolved a lot since then. It's really rich, not very healthy and tastes wonderful! If you want yours to be less rich, leave out some or all of the sour cream. I buy the low-fat or no-fat versions and that helps too.
Tater Tot Casserole
