Bread (toasted -- grainier types work well)
1 sweet potato or yam, peeled
A few slices of Granny Smith apple
Onion (Red onion is best)
1. Preheat your oven to about 315 degrees Fahrenheit and line a baking dish with aluminum foil.
2. Slice the sweet potato into circles about 1/8-1/4" thick. Butter both sides of the slices and arrange in the dish. Bake for about 15 mins, then turn over and bake for another 15 adding more butter if they seem dry. They should be pumpkin colored and feel soft when poked through with a fork. The baking time will depend on the thickness of your slices, so bake longer if you need.
When done, remove dish and drizzle a bit of maple syrup on the slices. Let them cool slightly.
3. Meanwhile, thinly slice the apple and onion. The amount used is to your taste. I prefer my sandwich with one layer of apples with a few small circles of onion sprinkled on top.
4. Spread goat cheese on the bread. Arrange sweet potato slices, apples, and onion on top. Drizzle a bit more syrup on, if you like.
