Rough chop the olives and add to a medium-sized mixing bowl with the green onion and set aside.
Using a food processor, whip the ricotta and Boursin together until they are light and fluffy. Add this to the bowl of olives along with the parmesan and Monterrey Jack cheeses.
Mix the olive/cheese mixture well. Add a healthy pinch of kosher salt and fresh ground pepper. Spread the mixture evenly over the bread halves. Add a little extra parmesan and Monterrey jack cheese to the bread halves. Don't be shy. Measure that extra sprinkle with your heart.
Bake the bread in a preheated 350° oven for 20-25 minutes or until the cheese is nice and melted.
If you would like to add a little color to the cheese, simply let the bread hang out under the broiler for just a few minutes at the end.
Attempt to let the bread cool down just a bit. Because it's hot. Slice and enjoy!
