01 - Heat 1/2 tablespoon olive oil in a nonstick skillet over medium heat. Add diced sweet potato, season with garlic powder, smoked paprika, salt, and black pepper. Cook, stirring occasionally, until sweet potato is tender and lightly browned, about 8 minutes. Transfer to a plate.
02 - In the same skillet, add remaining 1/2 tablespoon olive oil and chopped kale. Season lightly with salt and black pepper. Cook, stirring, until kale is wilted, about 2 minutes. Remove from heat.
03 - Place one flour tortilla in the skillet over medium heat. Evenly sprinkle half of the shredded cheese onto the tortilla. Top with the roasted sweet potato and sautéed kale, then sprinkle with the remaining cheese. Cover with the second tortilla.
04 - Cook the quesadilla for 2 to 3 minutes on each side, gently pressing with a spatula, until both sides are crisp and the cheese has melted. Transfer to a cutting board. Repeat with the second quesadilla if necessary.
05 - Allow the quesadilla to rest for 1 minute. Cut into four wedges and serve while warm.
