Classic & Easy Tuna Melt

I had this for lunch today and it was so good. I thought tuna melts were only for the oven. This way is so much easier.

Classic Tuna Melt
from Starkist.com

1 (6.4 oz.) pouch StarKist® Chunk Light or Albacore in water
2 tbsp. chopped onion
8 slices bread, toasted
1/2 cup mayonnaise
1-1/2 tbsp. chopped celery
4 slices cheese

In a mixing bowl, combine tuna, mayonnaise, onion, and celery; mix well. Top 4 of the bread slices each with 1 slice of cheese. Spread tuna mixture over cheese slices and top with remaining bread slices. Spread each sandwich with additional mayonnaise; place in skillet. Cook on medium heat until lightly browned on both sides.

Tip: carrot and cucumber may be substituted for onion and celery.
