Step 1

Cook it in an Instant Pot (note that this method requires 4 sweet potatoes to be cooked at once for the timing to be accurate). Or, you can bake it using these baking instructions, or prick holes in it and microwave it on high for 8-10 minutes until tender, turning halfway through. (Do this step in advance and refrigerate the sweet potatoes before cooking the quesadilla; the cook time below does not include this step.)

Step 2

Roughly chop the spinach. Warm the olive oil in a skillet and add the spinach, garlic powder, cumin, and a pinch of kosher salt. Cook until spinach is wilted and bright green, about 2 minutes, then remove it to a bowl.

Step 3

Cut the sweet potato in half and slide off the skin: place the flesh into a bowl and mash it with a fork. Spread 1/4 cup of the mashed sweet potato onto one tortilla. Drain and rinse the beans, then top the sweet potato with 1/4 cup of the black beans. Sprinkle sweet potatoes and black beans with a pinch of kosher salt. Then top with sprinkles of the cooked spinach (use your hands and leave any liquid at the bottom of the bowl). Top with 2 slices of cheese, tearing it as necessary to fit onto the tortilla. Cover with the second tortilla. Then repeat these instructions for the second quesadilla.

Step 4

Cook the quesadilla (or bake it in the oven): Lightly coat a skillet with olive oil and heat it to medium heat. Place one quesadilla in the pan, cheese side down. Cook for 2 minutes per side until lightly browned and the cheese is melted. Cut into wedges and serve. (Note: For lunch boxes, you can keep the quesadilla wedges refrigerated for a few days and place them into lunch boxes each morning.)
