Preheat the oven to 325˚F. Thinly slice all of your olives.

In a medium bowl beat together the butter and mayonnaise until completely combined. Add in the olives, green onions, and cheese and mix all together.

Slice the French loaf in half lengthwise, spread the mixture evenly over both halves of the loaf.

Place on a baking sheet and bake for about 25 to 30 minutes, until cheese is melted and a nice golden brown.
