Cut the French bread loaf in half to create 2 long pieces. Place on a large baking sheet, cut-side-up.
In a small bowl mix the softened butter, minced garlic, and oregano. Spread the butter mixture over both bread halves.
Chop the pitted olives and place them in a small bowl. Mix in the drained capers. Then sprinkle the olive mixture over the buttered bread halves.
Slice the salami and ham slices into thin strips. Sprinkle the “cold cut ribbons” over the bread.
Then top with shredded provolone and cheddar cheese. (If using provolone slices, you can either lay them over the cold cuts and sprinkle the cheddar over the top, or you can slice them thin.)
Bake for 10 minutes, or until the edges are golden and the cheese is melted. Immediately cut into 16 wedges and serve warm!
It does not matter at all if you use sliced or shredded cheese. I like to (at least) shred the cheddar and sprinkle it over provolone slices, so you can see the two colors of melted cheese. Flavor-wise it's exactly the same.
