Hot beef sandwich

I am trying out a new recipe for the crock pot.

4 lbs beef chuck roast
1 - 0.7 oz packet of dry italian dressing mix
1 tbsp italian seasoning
1 tsp garlic powder

Add ingredents to crock and cook on low for 8 hours. When done, break up meat; it should fall apaart. Serve on hoagie rolls. Melted cheese is optional.
