These quesadillas are perfect for fall. They are stuffed with butternut squash which are at their peak this time of year. You will have some leftover beans. Add them to any salad for extra protein, make some homemade nachos and incorporate the beans into the topping, or turn them into a black bean burger patty. The options are endless for leftover beans!
Cook the chorizo in a large nonstick skillet over medium-high heat, breaking it up with a wooden spoon, until browned, about 4 minutes. Remove to a large bowl, reserving the pan drippings.
Reduce the heat under the skillet to medium and add the squash, 1/3 cup water and 1/2 teaspoon salt; gently toss. Cover and cook until the squash is fork-tender, about 4 minutes. Uncover and cook until the liquid evaporates, 1 to 2 more minutes. Add the beans, chile powder and a pinch of salt and cook, tossing, until warmed through, 2 to 3 minutes. Add to the bowl with the chorizo.
Meanwhile, whisk the lime juice and 1 tablespoon olive oil in a small bowl. Put the kale in a large bowl and pour the lime dressing on top. Massage the dressing into the kale; season with salt.
Divide the squash mixture among the tortillas, leaving one half of each tortilla uncovered. Top with the cheese. Fold over the other half of each tortilla. Return the skillet to medium heat and add 1 tablespoon olive oil. Add 2 of the quesadillas and cook, flipping halfway, until golden, 3 to 4 minutes. Add the remaining 1 tablespoon olive oil and repeat with the remaining quesadillas.
Cut the quesadillas in half. Divide among plates and serve with the kale salad, pico de gallo and sour cream.
