Soften the butter and margarine. Press the garlic cloves over the butter and margarine, sprinkle with garlic salt and mix well
Let sit for several hours or overnight. Toast one side of the bread. When cooled enough to handle, spread the butter mixture on the untoasted side. Set under a broiler set at 375 and cook to desired crispness. Enjoy and let me know what you think. This mixture also tastes great on steaks.
