Here are a few quick things you can do with potatoes which don't involve waste, or more than a few minutes of your time and attention. I'm in love with potatoes, so I make these things often. They're so easy that I feel stupid for posting them.
No waste baked potatoes
Take a potato, poke some holes in it with a fork, rub some olive oil into it, throw it in the oven directly on the rack and bake at 400 for about 30 minutes. Viola. Potato. Who says you need aluminum foil to bake a potato?
(Charles, you can even do this in a toaster oven. It will take a bit longer.)
Take a potato, slice it into chips (very, very thin, if you can), place slices on a baking sheet, brush slices with oil, sprinkle on some salt, bake at 350 until crispy and amazing. Goodbye bagged potato chips. Hello saving money and resources!
Mashed purple potatoes
Take several purple potatoes, quarter them, boil them until soft, transfer to a bowl, add a bit of rice milk, salt, pepper, olive oil, a tiny dab of coconut cream (trust me. Dooo it), minced garlic and then mash. Mash some more. Mash a little bit more....... now STOP! ACK! YOU'VE OVER-MASHED IT!!!! No I'm kidding, it's ready, just eat. Side note: Isn't it super cool how the boiling water turns blue??!
French fries (but baked)
Take a few potatoes, slice into wedges, put into glass bake tray, coat the bottom with a thin layer of olive oil, add salt and pepper and garlic, bake at 350 until done. No need to flip. Seriously. You'll need ketchup and mustard for these. Spicy ketchup...mmm.
