Crock pot lasagna. Lots of recipes out there, I don’t even recall where I got the one we use. The key is to find one that doesn’t contain too much liquid so that the lasagna is watery. I recall we went through several versions before we found the one we use now.
Whatever you cook, first get yourself a healthy supply of those disposable crockpot liners. Golden. These things make cleanup SOOOOOOO easy.
