Preheat oven to 400°F. Wash and scrub sweet potatoes, and place in oven directly on rack. Place a baking sheet on rack below potatoes to catch any drips. Roast for 30-40 minutes or until fork tender.
While potatoes are roasting, prep veggies.
Add ground beef to a large skillet and cook until browned over medium heat.
When beef has browned, add pepper, carrots and onion to pan. Sauté until softened.
While veggies are cooking, whisk together tomato sauce, coconut aminos, molasses, apple cider vinegar, and mustard in a small bowl. Set aside.
Add garlic to veggies and saute for another 30 seconds until fragrant.
Add tomato paste and all dry seasonings, stir and cook for one minute.
Stir in whisked wet seasonings, turn heat to low and let simmer.
Remove potatoes from oven. Carefully remove peels and mash potatoes in a large bowl.
Transfer sloppy joe mix to a 9x13 glass baking dish.
Dollop the potatoes on top of the beef in an even layer. Top with a sprinkle of salt and pepper.
Bake in 400° oven for 10-15 minutes, until potatoes have crisped around the edges. Remove from oven and let cool slightly before serving.
