Preheat the Blackstone griddle over medium heat (to approximately 350 degrees F). Spread half of the butter out onto the griddle with the spatula and let it melt.

Add the diced onions to the grill and sauté them for 3-4 minutes until the onions are soft.

Add the remaining butter to the grill and allow it to melt.

Spread the hash browns out on the grill in a single layer on one side of the grill with the onions.  Toss until they are combined and then allow them to sit for the hash browns to brown.

On the other side of the grill.  Brown the diced sausage links.

Whisk the eggs with the milk, salt and pepper together in a bowl and add them to the grill and scramble them on the grill.

Allow the hash browns to cook for several minutes (do not move them) until they are browned on one side.  Once browned, flip them with a large spatula and cook them for several minutes on the other side until browned.

Once the hash browns are cooked, place the scrambled eggs, sausage and shredded cheese on half of the hash browns.

Flip the other half of the hash browns on top.

Turn the heat on the griddle down to low and heat for a few minutes until the cheese is melted.

Remove from the grill.  Serve warm and enjoy!
