Entered for safe-keeping, from Sean Donnellan's "Something Tastes Funny", recipe by Naidre Miller. This cookbook is for new cooks or non-cooks. It doesn't get much simpler than this. This can also be made as an appetizer by slicing cooked tuna thinly and serving on toast points with an avocado slice. The key is really fresh tuna if you don't want to be reminded of all that canned stuff from childhood. Marination time is included in the preparation time.
