Test Kitchen Tips:
For a quick start in the morning, cut the vegetables into pieces the night before, then refrigerate until you're ready to start cooking. Just remember to cover the potatoes with water to prevent discoloration; drain before adding to the slow cooker.
For best results, do not remove cover during cooking.
