Start by boiling your sweet potatoes and creating the mashed sweet potato topping.
Make the filling by browning ground beef, lamb and veggies, then adding tomato paste, flour and broth to form a gravy.
Add the sweet potatoes to the top of the filling.
Spread the sweet potatoes across the top of the filling in an even layer.
Bake the sweet potato shepherd's pie for 30 minutes in a 380 degree oven.
