I chop several sweet potatoes into rounds. For my husband and I and our young daughter, we can easily eat 3 good sized potatoes. I'd say at least one potato per person.
Put them in a bowl with a bit of olive oil and sea salt and mix them well (I like to use a plastic bowl with a lid so that I can just shake them around until they are well coated).
Spread them out evenly on an olive oil sprayed cookie sheet. Bake them at 350 F, for about 10-15 minutes each side, depending on how thick I slice them.
Enjoy! These are somewhat addictive!
