Begin by mixing the beef with seasonings of your choice, forming them into small, even-sized meatballs.
Place the meatballs on a baking tray and bake in a preheated oven until they're browned and cooked through.
While the meatballs are baking, peel and chop the sweet potatoes. Boil them in a pot of water until tender.
Once cooked, drain the water and mash the sweet potatoes with a touch of butter or cream, seasoning with salt and pepper.
Serve the meatballs on a bed of mashed sweet potato, garnishing with herbs or gravy if desired.
