Scrub 4 or more potatoes and prick with a fork. Wrap in aluminum foil and place in an empty slow cooker (do not add water). Cook 8-10 hours on low, or 2 1/2-4 hours on high.
See how easy it is? It's barely a recipe, but it may just change your life. You can load up the cooker with as many potatoes as you can fit in. I've made ten at a time in mine, and it's a dream in hot weather: you can avoid heating up the whole house.
Healthy toppings options:
Greek yogurt (thicker and richer than regular yogurt) and chives
Chunky garden salsa
Leftover stir-fried vegetables (Don't be afraid!)
Light creamed spinach
Mediterranean style: light feta cheese, kalamata olives, chopped bell pepper
