Grilled Sweet Potato Chips - Savory or Sweet

Tried these for the first time during an impromptu grill party on the roof. They were a pretty big hit, so here they are:

Grab some smallish sweet potatoes, preferably of the long and cucumber-like variety.

You will also need: salt (or seasoning salt), pepper, and olive oil.

For Sweet: Melt butter and brown sugar in a bowl with a little cinnamon

1) Peel the sweet potatoes and cut them across to make coin-shaped cuts, or "chips" (or crisps, if you are from England and don't understand that "chips" is pronounced "fries"). Make sure and cut them VERY thin so they cook up crispy and fast on the grill. Chip-thin

2) Throw the sweet potato coins into a plastic bag with some olive oil, salt, and pepper (or the butter and brown sugar concoction) and shake it up.

3) Spread the coins evenly over the grill and close the lid. CHECK FREQUENTLY

4) After about five minutes, flip them over and cook on that side for a while.

5) Do the taste test! Make sure they are cooked all the way through before serving.
