Bake yam for 40 to 45 minutes at 400 degrees.

Remove the yam from the oven, let it cool

When the yam has cooled, remove the skin and slice it into 1-inch bite-size cubes.

Melt 1 tablespoon of butter in a large skillet. Add onion slices and pecans and saute for a couple minutes or until onion slices begin to brown.

Add sliced yams, maple syrup and cinnamon, saute for 4 mins stirring often until the sweet potatoe pieces are hot.
