I cooked a meatloaf in my slowcooker the other day for the first time. DH really liked it, and I thought it was ok. the texture was a little different. Next time I will use less milk in the mixture -- it doesn't lose moisture like it does in the oven.
On the subject of cabbage rolls, I wish I had my mother's recipe for stuffed cabbage. Tried to reproduce it as best as I could remember, but it wasn't as good. These weren't rolls, but shaped like the entire cabbage with the large outer leaves as a shell and browned butter poured over the baked casserole. Oh lord it was good!
