Preheat oven to 350 degrees. Put ham and cheese inside the rolls and place in a 9x13 pan. Melt the butter and then add the Worcestershire, garlic powder, and poppy seeds. Pour sauce over the rolls. Then bake the rolls for 15-20 minutes or until the cheese is melted and rolls are golden brown.
Some people make these ahead and let them sit for a few hours. Then bake when they are ready. They are great for a quick easy dinner or for parties or big family gatherings.
