In a saucepan, cook margarine & flour until bubbly then slowly add broth & cream. Gently boil for a few minutes; add soya sauce, salt & pepper. Remove from heat & set aside.
Potatoes
Boil potatoes in salted water until tender but not overcooked; cut into 1/2-inch slices. Arrange them on the bottom & sides of a 8-inch round baking dish.
Meatballs
Preheat oven to 375 F. In a bowl, combine all meatball ingredients & form into balls. Arrange them over the slices of the potatoes on the bottom of baking dish. Use the remaining potato slices to create ‘walls’ between each meatball.
Pour white sauce into each meatball ‘pocket’. Sprinkle entire dish with grated mozzarella cheese. Bake 45 minutes or until meatballs are cooked & cheese is golden.
Recipe Notes
You can definitely use whatever ratio of meat combo you prefer or just use one one type, your choice.
