Cook beans and garlic in water until tender (about 2 hours). Drain, and puree, or whirl in blender until smooth, with cream or olive oil, tuna, and a little bean liquid. When smooth, season to taste with salt, and add the cheeses. Place in shallow baking dish (I spray dish well) dot with butter and sprinkle with bread crumbs (I often add more bread crumbs). Bake 375� for 20 minutes or until hot and brown.
