Hot Tuna Melt on English Muffin

Ingredients:
4 oz Canned Light Tuna (water packed and drained)
2 Tbsp Finely Diced Celery or Onion
1 ½ Tbsp Non-Fat Cream Cheese
1 ½ tsp Lemon Juice
1 Whole Wheat English Muffin (halved and lightly toasted)
1 Tbsp Shredded Reduced Fat Cheddar Cheese (or desired choice)
1 Slice of Avocado (optional)
1 Slice of a Tomato
salt and pepper (to taste)

Directions:
Preheat oven to 400 °F. Rinse and drain tuna until all additional water is removed. Combine tuna, celery or onion, cream cheese, salt, pepper and lemon juice in a small bowl. Scoop tuna mixture onto each muffin half. Sprinkle cheddar cheese over each tuna-topped muffin. Place both halves in broiler or toaster oven and heat until cheese is melted, 1-2 minutes, watching carefully to prevent burning. Finish with a slice of tomato and avocado on top.
