If you want to make homemade mayonnaise yourself, do not miss this recipe. Separately, chop the onion or cut it into julienne strips and mix it with the previously drained tuna. If you wish, you can pass the onion a little through the pan. Fill the bread with this mixture and voila! You already have your onion sandwich with tuna finished. You can also add lettuce and cheese if you wish.
