Tarragon Tuna Melt - cooking recipe

Ingredients

1 thinly sliced green onion, including the greens
3 tablespoons chopped fresh flat-leaf parsley
2 tablespoons chopped fresh tarragon leaves or 2 teaspoons dried tarragon, crumbled
zest of one lemon
2 teaspoons lemon juice
1 teaspoon Dijon mustard
1/8 teaspoon fresh ground black pepper
1/3 cup mayonnaise
2 (6 ounce) cans solid white tuna, well drained and flaked
8 slices French bread (or your favorite bread) or 8 slices Italian bread (or your favorite bread)
1 thinly sliced tomatoes (8 slices)
4 ounces grated sharp white cheddar cheese (about 1 cup)
2 tablespoons softened butter

Preparation

Mix the green onion, parsley, tarragon, lemon juice, lemon zest, Dijon mustard, black pepper, and mayonnaise in a medium sized bowl. Add the drained tuna, mixing with a fork to break up the flakes.
Lay out four slices of bread. Divide the tuna mixture evenly onto the slices. Top each bread slice with tomato slices and grated cheese.
Spread one side of the remaining four bread slices with butter.
Place bread slices, buttered side up, on top of the cheese.
Heat a large griddle, on medium heat.
Place the sandwiches, buttered side down, onto the hot griddle. Gently spread butter on top of the bread slices.
Cook for about 3 minutes, or until nicely browned on one side.
Carefully turn them to the other side. Cook for another 3 minutes or so, until the second side is browned.
Serve immediately.
