Scrub potatoes, wipe dry, and place on a baking sheet. Bake 45-55 minutes, or until potatoes are tender when pierced with a fork.
Cut the potatoes in half lengthwise. Carefully scoop the flesh out of the potatoes and place in a medium-sized bowl. Reserve the skins. With the back of a fork, mash the potato innards until most lumps are gone.
Stir in the olive oil and 1/2 teaspoon of the cumin. Divide the mashed sweet potato evenly between the potato skins. Place on a baking sheet.
Heat a large nonstick skillet over medium-high heat. Lightly coat with cooking spray. Add the ground turkey and cook, breaking up into small chunks as it cooks. Once cooked through, stir in the garlic, chili powder, remaining cumin, and chili powder. Cook for 1 minute. Stir in the crushed tomatoes.
Change the oven temperature to broil. Spoon the turkey mixture into each sweet potato skin on top of the mashed potato fill. Top each with shredded cheese. Broil until the cheese is melted, about 1 minute. Remove from the oven and sprinkle cilantro on top. Serve and enjoy!
