In a large pan set over medium heat, sauté the onions and garlic in 2 tbsp of the oil until the onions are cooked.

Add the grated sweet potatoes, chili powder, cumin and cayenne and cook for about 10 minutes. When the sweet potato is tender, add salt and pepper to taste and remove the filling from the heat. Squeeze ½ a lime over the sweet potatoes and mix.

For the Vegan Queso... Combine all ingredients (except water) in a high-speed blender or food processor and process until smooth. Gradually add in the hot water while processing to form a smooth mixture. You don't want this to be too runny.

To cook the quesadillas on the stovetop, heat 2 tsp oil over medium heat in a large frying pan. Fill tortillas lightly, with sweet potato filling and some Queso Cheese. Fold them in half and place into the heated frying pan. Cook two at a time until golden, about 2 minutes then flip. Cook until golden, about 2 more minutes. Repeat with remaining tortillas and Queso Cheese.

Serve fresh lime wedges, some salsa and fresh cilantro!
