Preheat your oven to 350°F (175°C).

Chop the pimiento-stuffed green olives and black olives, and thinly slice the green onions.

In a large mixing bowl, combine the softened butter, mayonnaise, and grated Monterey Jack cheese. Stir in the chopped olives and sliced green onions.

Slice the French bread lengthwise down the center, creating two halves.

Spread the creamy olive-cheese mixture evenly across both halves of the sliced French bread.

Place the prepared Olive Cheese Bread onto a baking sheet and bake for 20 to 25 minutes, or until melted and golden.

Let it cool for a few minutes before serving, bake for an additional 5-7 minutes if the top isn't as brown as desired.
