Preheat the oven to 350° F (176° C). Slice the peppers in half and scoop out the seeds. Place on a baking sheet and bake for 10 minutes (remove and set aside after baked).
While the peppers are baking, heat a large skillet over medium heat.
Add sweet potatoes and diced tomato into the skillet and sauté until the sweet potatoes begin to soften and the tomatoes roast (about 8-10 minutes).
Add the ground beef to the skillet with the sweet potatoes and tomatoes.
Once the ground beef is cooked through, season with paprika, chili powder, coriander, and all spice.
Divide and pour the meat mixture into the peppers, top with cheddar cheese and place back in the oven for an additional 10 minutes.
