For the tuna, we found a big flavor and texture difference by using the solid white chunk albacore tuna vs the chunk light style tunas. Some are chunkier and some are more mushy so add the amount of mayo to your preferred taste. Some folks like their tuna extra creamy and some like it drier, with less. So add accordingly!
