Heat oven to 375°F. Brush 12 regular-sized muffin cups with shortening and line them up with the cut nori seaweed. Set aside.
In a 10-inch skillet, cook beef, salt, onion, and garlic over medium-high heat for 5 to 7 minutes. Stir frequently, until ground beef is cooked then cool for 5 minutes.
In a medium bowl, stir baking mixture ingredients with a whisk or fork until blended. Spoon 1 tablespoon baking mixture into each muffin cup. Top with about 1 tablespoon ground beef mixture. Spoon another tablespoon of baking mixture onto ground beef mixture in each muffin cup.
Top with spring onions and cheeses
Bake for about 30 minutes or until tops of muffins are golden brown and a toothpick inserted in center comes out clean. Cool for 5 minutes. With a thin knife, loosen sides of pies from pan. Remove from pan and place top sides up on cooling rack. Cool for 10 minutes longer before serving.
