Have you ever substituted squash for the corn?
I haven’t tested this as a squash casserole. My best guess is, it likely would work using steamed squash with as much liquid removed as possible. We’d love to know how it goes, if you try it!
So so good 😊
Can a layer if chili with meat and beans be put in the middle?
I haven’t tested that but if you try it, let us know how it goes!
