Meanwhile, preheat your oven to 425 degrees. Combine the other stick of softened butter, 3 cloves minced garlic, mayonnaise, shredded cheese, & the other half of the green onions. Cut your french bread in half lengthwise, & hollow out the insides halfway. Spread on the butter/mayo mixture. Bake for 7-10 minutes, or until the bread is toasty.
