Preheat oven to 400 degrees Fahrenheit. Line a baking sheet with parchment paper and set aside.
Place diced sweet potato in a medium sized microwave-safe bowl. Cover the sweet potatoes with water and heat for 4-5 minutes until sweet potatoes are soft when pierced with a fork. Carefully, strain the water.
In a food processor or high-speed blender, blend cooked sweet potato, refried beans, spinach, cilantro, coconut oil, salt, and lime juice until smooth.
Using a spoon, spread 2-3 small scoops of the bean mixture onto the center of the tortilla, forming a line down the center.
Next, sprinkle cheese on top of the bean mixture.
Roll tortilla up as tight as you can and place it on a parchment-lined baking sheet, seam side facing down. Repeat with the remaining bean mixture and tortillas, placing them in a single layer on the sheet pan.
Bake in the oven for 10-15 minutes or until tortillas are firm and golden brown and the cheese is melted. I like flipping mine after 10 minutes and baking for another 5 minutes, but you don't have to flip them!
