Preheat oven to 400 degrees F.

In a food processor add the corned beef and pulse to grind the meat.

Add the corned beef, ground beef, salt, pepper, and egg in a large bowl and mix well.

Form the meat into meatballs. This batch made 30 meatballs for me. Keep in mind the size of the toast when making them.

Add some oil to an oven-safe pan and brown the meatballs.

When the meatballs are browned, sprinkle the sauerkraut over them and then top with the shredded cheese.

Bake for 15 - 20 minutes. You may want to pop it under the broiler afterward to brown the cheese.

Serve with mini toast and Thousand Island dressing.
