Step 1

Preheat oven to 350 degrees F. Cut the tray buns in half horizontally, while keeping them all connected. Roll each slice of deli corned beef loosely and place on top of the buns.

Step 2

Lay out the cheese so that it covers the entire surface of the buns.

Step 3

Sprinkle the sauerkraut over top the cheese as evenly as possible.

Step 4

Drizzle the dressing on top of the sauerkraut. Use as much or as little as you like, but approximately 1/4-1/3 of a cup should do it.

Step 5

Replace the top portion of the buns. In a bowl combine the melted butter and poppy seeds. Brush over the tops of the buns, spreading it as evenly as possible, letting it fall into the crevices of the buns. Bake for approximately 10 – 12 minutes or until the tops are golden brown.
