I prepared the onions with tuna sauce using Tropea onions, which have a sweet and delicate flavor. Of course, you can also use other sweet and high-quality red, white, or yellow onions. The onions are first cooked in sweet and sour sauce, and then when they are cold, they are seasoned with the tuna sauce. I recommend leaving them in the fridge for a few hours before consuming them for an even tastier experience. If you like vegetables with tuna sauce, also try CHERRY TOMATOES WITH TUNA SAUCE and mayonnaise and CELERY BOATS WITH TUNA SAUCE."}
