Veggie mince.. depends what kind. If cooking from dry, put it in early. The earlier the better, to get rid of that cardboard flavour. If it's canned Casserole Mince, put it in late. I love that stuff. It's wacky, it shouldn't be food, it's a bit of a sometimes thing for us, but I love it when we have it.

Yes you can freeze stuff after it has been cooked in a sauce. Bean purees and hommus freeze quite well too.

Enjoy!
