I don't cook many meals, but they tend to be big ones. I love the simplicity of a slow cooker. In eight hours, you can probably cook a post oak tree. Keep it simple, and it tastes good.
I put three or four thick pork chops on a bunch of potatoes that are cut into about eight sections and layered on the bottom. Two packages of frozen corn are layered over the chops. I use one fresh garlic section that I embed in a can of Campbell's Cream of Mushroom soup and spread over the chops. Add a half cup of water and wait eight hours. The meat will fall off the bone..
It needs a little garlic. But, even two cloves is too much. One clove is adequate. Salt and pepper to your own taste. Not a lot of work in that.
Pot roast is similar. I usually use frozen beans and a package of little carrots with about three sectioned potatoes. Works on a small roast nicely. I do use a pot roast seasoning package. Any of several will do. Again, not much work, and you probably have three days worth of meals for two or three.
