In a small bowl mash the cream cheese, using a fork. Add the cilantro, mozzarella cheese, green onion and olives. Mix well and add salt if needed.
Cut the baguette into 3 pieces.
Use a long knife to hollow out the insides.
Stuff the bread pieces with cream cheese mixture.
Slice the baguette into slices that are approximately 1 inch thick.
Tear 3 pieces of heavy duty foil. Place 5-6 of stuffed slices on the foil and fit together. Melt the butter. Brush the bread with melted butter.
Preheat the oven to 350 degrees F. Wrap the foil around the bread. Place them on a baking tray.
Bake in the oven for 15 minutes. Unwrap the bread and bake for 5 more minutes, or until the top browns slightly.
