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 (I use garlic salt or something called crazy salt). Bake for 20
minutes, turn, sprinkle that side, and bake for another 10 minutes.
