Tuna Melts

4 thick slices bread, white or wheat
1 T olive oil
2 7-oz cans solid white tuna in water (or any tuna you prefer)
1⁄4 c minced red onion, or any sweet onion
1⁄4 c diced celery
1 t Dijon mustard
1 T minced fresh dill, plus more for garnish
1 T minced fresh parsley
1 T lemon juice
1⁄2 c mayonnaise
4 oz grated cheddar cheese
1 avocado, sliced
Smoked paprika
Kosher salt and black pepper

Preheat the broiler.

Place bread slices on a sheet pan, brush lightly with olive oil, and toast until golden on one side. Remove from the oven and turn each slice over to the untoasted side.

Mix together tuna, onion, celery mustard, herbs, and lemon juice in a medium bowl. Use a fork to flake the tuna. Add the mayonnaise and gently fold in. Season with 3⁄4 teaspoon salt and 1⁄2 teaspoon black pepper. Taste first, then add more if needed.

Spread a quarter of the tuna mixture on each slice of bread, spreading to cover the entire slice of bread. Sprinkle each with a thick coating of cheese. Broil for 1-2 minutes until cheese is melting and lightly browned. Remove from the oven and sprinkle each with a little smoked paprika. Add avocado slices to each piece of bread. Serve immediately
