In a medium bowl, combine the pumpkin, cheese, cumin, coriander, chile powder, salt, jalapeno, and green onion. Mix until combined.
Heat 1 teaspoon oil in a large skillet over medium heat. Add half of the pumpkin mixture to one half of one tortilla and fold the other side of the tortilla over to create a half moon quesadilla. Carefully place in the pan, cover with a lid, and cook until browned, about 2 minutes. Flip and cook until both sides are browned and the cheese is fully melted and the quesadilla is heated through. Repeat with the remaining oil, tortilla, and pumpkin mixture.
Meanwhile, combine the sour cream, lime juice, and smoked paprika in a small bowl. Stir until combined. The mixture will be thick, so thin with a small spoonful of water if desired.
To serve, slice each quesadilla into 3 equal portions and top with sour cream, cilantro, and jalapeno slices.
Notes
If you have a large enough skillet, you can cook both of the quesadillas side by side to save time.
Make sure that you use 100% pumpkin puree and not pumpkin pie filling.
If you don't have colby jack cheese, any mild cheese that melts well will work. We recommend swapping for mild cheddar, shredded mozzarella, or pepper jack (if you like more spicy heat).
Add black beans or pinto beans to the pumpkin mixture for an even heartier pumpkin quesadilla.
If the sour cream mixture is too thick for you liking, add a small spoonful of water to thin it until you get your desired consistency.
If you don't have pumpkin, you can swap for butternut squash puree or sweet potato puree.
If you have homemade pumpkin puree, that's wonderful! Go ahead and use that as long as it's not sweetened or spiced with pumpkin pie spice.
