Ingredients

  • 6 1/2 oz. can tuna, drained
  • 1/4 cup chopped onion
  • 1/3 cup chopped celery
  • 1/2 cup shredded Mozzarella cheese
  • 1/2 teaspoon parsley flakes
  • 1/8 teaspoon salt
  • dash of pepper
  • 2 tablespoons mayonnaise
  • 3 hamburger buns
  • 1 tablespoon margarine, softened

Instructions

  1. Combine tuna, chopped onion, chopped celery, shredded Mozzarella cheese, parsley flakes, salt, pepper, and mayonnaise in a bowl.
  2. Mix well until all ingredients are evenly incorporated.
  3. Separate the hamburger buns into halves.
  4. Spread the cut sides of the buns with softened margarine.
  5. Spread the tuna mixture evenly on the cut sides of the buns.
  6. Place the prepared buns on a baking sheet and broil until golden brown.

Tips & Substitutions

For a creamier texture, consider adding a bit more mayonnaise or substituting Greek yogurt for a healthier option. Chopped bell peppers or pickles can also enhance the flavor profile. If you're out of mozzarella, any melty cheese like cheddar or Monterey Jack will work. For added crunch, toss in some crushed potato chips before broiling.

Serving Suggestions

Serve these Tuna Oven Sandwiches with a side of mixed greens or a fresh coleslaw for a light meal. They pair wonderfully with a bowl of tomato soup, making it a comforting combo. For a fun twist, consider serving with potato chips or a pickle on the side for extra crunch.

Storage & Reheating

Store any leftover tuna mixture in an airtight container in the refrigerator for up to 2 days. To reheat, place the filled buns under the broiler for a few minutes until heated through and the cheese is melty. Alternatively, you can microwave them for about 30 seconds, but broiling gives a better texture.
