Tuna Melt

As you can tell from my last few posts, I have been in a sandwich mood...breakfast, lunch and dinner! 
This tuna melt was very satisfying and was a good source of protein.

serves 4 ( 6 points+)

• 1 can ( 7 oz.) tuna packed in water, drained
• 3 T. canola mayonnaise
• 1 celery stalk, finely chopped
• 2 T. red onion, finely chopped
• 1 tsp. dried dill
• 1 Roma tomato, sliced thinly
• 4 slices 2% American cheese
• 4 sandwich thins (100 calories)

In a medium bowl, combine the first 5 ingredients. Spoon 1/4 of mixture onto each of four sandwich thins. Top with tomato and cheese. 
Spray a nonstick skillet with cooking spray. Grill until cheese is melted and sandwich thins are browned and toasted.
