Fall Black Bean Dip

I was thinking caramelized onions would be great on top in place of the green onions here,

2 c. refried black beans (for a recipe click here or canned works fine)
1 large sweet potato
2 Tbsp butter
Salt & Pepper to taste
small pinch cinnamon and nutmeg
Large dash cumin
Cayenne pepper to taste (optional)
1 c. sour cream
Green onions, sliced

Corn chips or crackers to serve (I used the Food Should Taste Good brand multi grain chips)

Prick sweet potato with a fork a few times on both sides and bake until tender. When cooked remove center from the skin and mash. Add the butter and seasonings to taste.

Spread black beans in the bottom of a 9x9 pan. Top with mashed sweet potato. Spread with sour cream and top with green onions.
