• sweet potato
  
• vegetable cooking spray
  
• favorite spice (I use garlic salt or something called crazy salt)
  

Heat oven to 350. Peel sweet potato (works with yams too) and slice
thin, as if for a thick potato chip. Cover a cookie sheet or baking
pan with foil, sprayed lightly with vegetable spray. Lay sweet potato
chips on the foil, rubbing each one slightly in the veggie spray.
Then lightly spray the tops with veggie spray, sprinkly with your
favorite spice. Bake for 20 minutes, turn, sprinkle that side, and
bake for another 10 minutes.

Make a lot, because EVERYONE including small children, SO's and
teenagers who usually stick up their noses at healthy food, tend to
like these.
