Tuna melts with a zing of Dijon and the crunch of celery and red onion!
I've made plenty of tuna melts over the years and I am not sure if I've ever made any with red onion. I think it's a fantastic addition to tuna salad and goes along really well with the Dijon instead of yellow mustard in the recipe. I'd love to try this particular recipe with bagels - years ago, I tried a recipe for chicken salad on a bagel and fell in love. It's my favorite vessel for chicken salad.
