Preheat oven to 375F. Slice the bread into 2 inch sections, making sure to not go all the way to the bottom of the bread.
In a small bowl mix together your melted butter, garlic, salt & oregano. Drizzle this mixture in between the bread sections making sure to get it all in there. In another bowl mix together your ham and cheeses. Now stuff your ham & cheese mix into the sections and top off the bread with more butter. Bake for 10-20min. Until nice and golden and all the cheese is melted.
