Best Tuna Melt Sandwich

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.

What you need:

• 4 cans (4 oz each) tuna, drained
• 1/4 cup mayonnaise
• 1/4 cup finely chopped celery
• 1/4 cup finely chopped red onion
• 1 Tbsp. dijon mustard
• 2 Tbsp. chopped parsley
• Salt and pepper
• 8 slices bread (I used French)
  
• Sliced cheddar cheese
• Sliced tomato
• 1/4 cup softened butter or spread
  

Directions:

1. In a medium-sized bowl, combne tuna, mayo, celery, red onion, mustard, parsley, salt and pepper.
2. Spread butter on bread. Toast under a broiler until lightly golden brown.
3. Add a slice of cheese, some of the tuna mixture, a tomato, and more cheese.
4. Broil until cheese has melted.
