Pierce sweet potatoes 5-8 times with a fork. Place them on a foil lined baking sheet and roast for 45-55 minutes or until they are super fork tender. Remove and set aside.
Place a pan over medium high heat and add oil to the pan.
Add ground beef to the pan and cook, breaking up the meat, until it is cooked through (about 5-8 minutes).
Add tomatoes, tomato paste, water, chili powder, garlic powder and paprika and stir to combine. Let simmer for 5 minutes for all the flavors to combine and thicken. Season with salt and pepper to taste.
Slice sweet potatoes down the middle and scoop in chili!
