Sweet Potato Quesadillas

Sweet Potato Quesadillas (from Moosewood Restaurant Cooks at Home)

1 1/2 cups finely chopped onion
2 garlic cloves, minced or pressed
3 Tbsp vegetable oil
4 cups grated peeled sweet potato
1/2 tsp dried oregano
1 tsp chili powder
2 tsp ground cumin
generous pinch of cayenne
salt and ground black pepper to taste
1 cup grated sharp cheddar cheese

8 tortillas (8- to 10-inch)
tomato salsa
sour cream

Saute the onions and garlic in the vegetable oil until the onions are translucent. Add the grated sweet potatoes, oregano, chili powder, cumin, and cayenne and cook, covered, about 10 minutes, stirring frequently to prevent sticking.

When sweet potato is tender, add salt and pepper to taste and remove the filling from the heat. Spread one-eighth of the filling and 2 tablespoons of the cheese on one half of each tortilla. Fold in half, and heat in skillet on each side until lightly browned. Serve with salsa and sour cream.
