Preheat the oven to 425 degrees. Pierce the sweet potatoes all over the skin with a fork. Rub the outside of the potatoes with olive oil and cover with foil.
Bake in the oven for 1 hour until fully cooked.
Brown the ground turkey in a skillet on medium heat. Once it's finished cooking, add the onion, bell pepper, and garlic.
Mix well. Cook until the mixture is fully cooked and starts to crumble.
Stir in the garlic, water, tomato paste, and tomato sauce. Stir until mixed well. Turn heat down to low and simmer for 20 minutes, stirring occasionally.
Remove the sweet potatoes from the foil and slice down the middle. Mash up the insides with a fork and pour the sloppy joe mix over sweet potatoes.
