Potato, Cheese & Ham Casserole

26 oz. bag of hashbrowns
2 cups colby jack cheese, shredded (8 oz)
10 oz. ham, cut into chunks
1/4 cup onion, minced
1 cup milk
1/2 cup beef stock or broth
2 tbsp. butter, melted
1/4 tsp. garlic powder
1 tsp. salt
1/4 tsp. pepper

Preheat oven to 425.  In a large bowl, combine hashbrowns, cheese and onions.  Combine, in a separate bowl, the milk, broth, 1/2 of the butter, garlic powder, salt and pepper. Mix well, then pour over the hashbrown/cheese mixture and mix well.  Heat the remaining butter in a pan.  Cook potato mixture, stirring occasionally, until heated through and all the cheese is melted, about 7 - 8 minutes.  Transfer to a baking dish and put in the oven to bake for 45 minutes to an hour.
