Prick the sweet potatoes several times and bake in the oven for 30-45 minutes on 450º, or until soft. (Baked sweet potato instructions here. Microwave instructions here.)
Add the beef, tomato paste, and seasonings to a large pan or pot over medium heat and brown, adding a little water if necessary. Remove and set aside. (Leave the drippings in the pan.
Sauté the onions in the beef drippings for a couple of minutes, then add the garlic, mushrooms, bell pepper, and carrot. Add a little more salt and sauté for 5-8 minutes, or until nicely cooked.
Add the beef and chopped greens to the pan and sauté until wilted.
Cut the sweet potatoes open and fluff up the flesh a bit. Divide the filling evenly among the 4-6 potatoes and serve!
*One full sweet potato might be a bit much per person so feel free to serve half a sweet potato instead. This should serve between 4-6 people. If you’re not Paleo and you load this up with black beans, you can easily double the servings for only $1-$2 more!*
