I have done it with pot roast and chili and broth. Cooked overnight. Ate it for breakfast, turned it off. Stuck the crock in the refrigerator. Got it out at night and put it back in the base and let it warm up on low to eat, and set it to warm to hold it if Hubby wasn’t home yet.
When in a hurry, I just take a serving out, plop it on a microwave safe plate (paper - no washee needed), cover with splatter shield or waxed paper, and dinner’s ready in a minute. No additional pot!
