Tuna Melt Tostadas

I love to cook, because seriously who wants to take four kids to a restaurant? All kidding aside, I love to try to new foods and my family is usually pretty open to my ideas.

Instead of sandwich bread, this tuna melt sits pretty on a crunchy tostada, topped with lettuce, tomato, avocado and sour cream.

Serves: 3 Save

Ingredients (12)

  • 1 (15-oz) can tuna in water, drained
  • 1/3 cup reduced-fat mayonnaise
  • 2 tablespoon spicy brown mustard
  • 1/4 cup dill relish (like Heinz)
  • 1/2 teaspoon salt, plus more for topping
  • Pepper
  • 6 corn tostadas
  • 1 cup shredded sharp cheddar cheese
  • 1 head romaine lettuce, sliced into ¼-inch strips
  • 4 Roma tomatoes, diced
  • 1 avocado, diced
  • Light sour cream

Directions

  1. Preheat oven to 375° F. Stir together tuna, mayonnaise, mustard, relish, salt and pepper in a bowl.
  2. Spread the mixture evenly over each tostada and sprinkle cheese on top. Bake 8 minutes, until cheese is melted and tostada edges are just starting to brown. Remove from oven and top with lettuce, tomato, avocado, sour cream, salt and pepper.
