I was inspired by some chocolate-covered potato chips in a canister at the convenience store, but of course they were expensive and the chocolate wasn't fair trade. So I bought some ridged potato chips, and my son helped me melt some fair-trade dark chocolate and coconut oil together, then he dipped the chips in and laid them on a silicone baking sheet before putting in the fridge to set.
They were so delicious that we then tried it with some salted popcorn, too, and my son suggested dried cranberries as well. We used the same chocolate and coconut oil mixture. Yummy!
