Preheat your oven to 200°C / 400°F.
In a roasting pan, combine peeled and diced butternut squash, jalapeños, and diced onion.
1 large butternut squash, 1 medium yellow onion, 1 medium jalapeño pepper
Add olive oil, cumin, chili powder, smoked paprika, and a touch of salt and pepper. Give this a good mix so that everything is well seasoned.
1 Tablespoon extra virgin olive oil, 1 teaspoon ground cumin, 1 teaspoon chili powder, 1 teaspoon smoked paprika, 1 teaspoon salt, ½ teaspoon freshly ground black pepper
Place in the oven and roast for about 20 - 30 minutes, stirring once about half way through. The squash should be tender when the vegetables have finished roasting.
Remove the roasting pan from the oven and roughly mash about half of the squash in the pan. You want some chunks and some mushy parts, which will help the burrito filling hold together.
Add in the black beans, quinoa, cilantro, and lime juice directly to the pan. Stir to combine.
28 ounces black beans, 2 cups cooked quinoa, ½ cup fresh cilantro, 1 medium lime
Spoon about ⅙th of the mixture into a large whole wheat tortilla. Add a bit of cheese if desired. Fold the sides of the tortilla in, and roll up to form a burrito. Repeat with remaining filling.
6 large whole wheat tortillas, 1 cup shredded cheddar cheese
Serve the burritos immediately, or toast them in a dry skillet or warm oven until crisp and golden.
