While vegetables are sauteing, dice 1/2 lb. cooked ham.
When vegetables are done sauteing, allow them to cool.

On top of the hash browns, add 1/3 of the chopped ham.
Add 1/3 of 1 1/2 cup shredded cheese to top of chopped ham.
Add 1/3 of the sauteed vegetables to the top of the cheese. Now, repeat this process twice, starting with the hash browns and adding layers in order.

Add 1/4 teaspoon salt and 1/4 teaspoon pepper, or adjust to taste.
Whip thoroughly.
