My husband loves tuna sandwiches. He could very happy eating those every day for lunch the whole year if I let him. Tuna is also not the cheapest thing on the planet. But I have learned that the more you put in it, the farther it goes... Now this may be old news to many of you, and many of you may have been doing it for years, but for those who have never thought of it... just a few ideas. Some of the things I regularly put in our tuna before putting it on bread: * mayonaise * mustard * onion * celery * chopped up pickles * hard-boiled egg I know other people who put chopped up apple pieces & olives in their tuna as well. I love this as it often lets me use up things I have in the fridge anyway and stretches a can for a few more sandwiches. I would love to hear any other suggestions you have to stretch our tuna!
