I use to eat tuna the way my mom made it. Which is absolutely light and delicious, until I met my husband...I saw the way he made his but never thought i would even begin to like it seeing as that it has a bit of sweetness to it, and i had never ever grown up eating my tuna sweet in any way. My mom always made hers with seasonings and celery and onion....But one day i tried some of his tuna in a melt thinking that the cheese would be amazing with it...AND IT WAS AWESOME. I put a few differet seasonings in it than him and just made it my own and i like it his way and my own just the same. Now i pretty much only eat this tuna But of course on occasion at mom's I eat the tuna I still love and grew up with. They are polar opposites though I must say. I don't really measure my ingredients so it may be a little hit or miss. It all depends o how mayonaise-y you like it or how sweet. BUt i wil post al ingredients. I also love to serve these halves with Campbell's Tomato soup using heavy cream instead f milk and cooking slowly as not to burn. AMAZING. Especially on a cold night!
