Preheat the oven to 220°C (425°F) with a rack in the centre. Line a baking sheet with parchment.
Cut the sweet potato into 1.5 cm (1/2 inch) cubes, toss with the oil and roast for 20 minutes, until tender and browned.
Meanwhile, heat a large skillet over medium-high heat. Add the turkey with the chili powder and cumin and cook, breaking it up, until it reaches 74°C (165°F), about 7 minutes.
Stir in the black beans, roasted sweet potato and salsa and cook over medium heat for 3 minutes until hot.
Warm the tortillas for 20 seconds in the microwave so they fold without cracking.
Spoon the filling down the centre of each, sprinkle with cheddar, fold in the sides and roll up tightly.
Eat right away, or wrap in foil and freeze. Reheat from frozen in the microwave, unwrapped and in a damp paper towel, for 3 to 4 minutes, turning halfway.
