Peel and cut your sweet potato into small chunks, about 2 inches in diameter
1 small sweet potato
Boil sweet potatoes in 10 cups of hot water until tender—about 15 minutes. You'll know your potato is ready because you will be able to easily pierce it with a fork.
Slice your onions and cook them in a pan with 1 tablespoon of butter until caramelized.
1 medium yellow onion
Meanwhile, drain and rinse your black beans and set aside.
1 can black beans
Once sweet potatoes are tender, throw them in a blender or food processor with the remaining butter, milk, cream cheese, cayenne, cumin, salt and pepper to form a puree. 2 tablespoons butter, 2 tablespoons milk, 2 tablespoons cream cheese, ¼ teaspoon cayenne pepper, 1 teaspoon cumin, 1 pinch of salt and pepper
Lay your tortilla flat on a clean surface and spread your puree over half. Top with caramelized onions, strained black beans, and about 1/2 cup of cheddar cheese.
1 cup shredded cheddar cheese, 2 XL flour tortillas
Fold your tortilla in half so that the filling is covered. Place a medium-sized nonstick fry pan on your stove over medium heat.
Once your pan is hot, place your quesadilla directly on to the pan and cook for about 3 minutes until the tortilla is golden brown.
Flip and cook for another 3 minutes until both sides are crispy and the cheese is melted.
Repeat steps 5 & 6 with your second tortilla. Serve hot on its own or with or salsa!
