Ingredients
  

  • 2 cans tuna drained (5 ounces each)
  • 4 large butter croissants
  • ½ cup mayonnaise
  • 1 tablespoon Dijon mustard
  • 1 tablespoon lemon juice
  • 2 celery stalks finely chopped
  • 2 tablespoons red onion finely chopped
  • 2 tablespoons chopped fresh parsley

Method
 

Cooking Instructions
    Prepare the Tuna
    1. Drain the canned tuna very well. Place it into a large bowl. Break it into small pieces using a fork. Removing extra liquid helps keep the filling creamy instead of watery.
    Mix the Dressing
    1. Add mayonnaise, Dijon mustard, lemon juice, garlic powder, salt, and black pepper into the bowl. Stir until everything becomes smooth and evenly combined.
    Add Fresh Vegetables
    1. Mix in the chopped celery, red onion, and parsley. Stir gently until every ingredient is coated with the creamy dressing. The vegetables add freshness and crunch.
    Taste and Adjust
    1. Taste the tuna salad. Add more lemon juice for brightness or a little extra pepper for stronger flavor. Mix again before using.
    Prepare the Croissants
    1. Slice each croissant across the middle without cutting all the way through. Open them carefully so they stay soft and fluffy.
    Add Fresh Vegetables
    1. Place lettuce leaves on the bottom half of each croissant. Add tomato slices and cucumber if using. These vegetables keep the sandwich fresh and colorful.
    Fill the Sandwich
    1. Spoon the tuna salad generously over the vegetables. Spread it evenly for the perfect bite every time. Add cheese if desired.
    Close and Serve
    1. Place the top half of the croissant over the filling. Serve immediately while the croissant stays fresh, flaky, and soft.

    Notes

    • Drain the tuna completely.
    • Use fresh bakery croissants.
    • Chill the tuna salad for 20 minutes.
    • Chop vegetables into small pieces.
    • Add fresh herbs for extra flavor.
    • Do not overfill the sandwich.
    • Use crisp lettuce for freshness.
    • Add avocado for a creamy texture.
    • Fresh lemon juice gives better flavor.
    • Serve soon after assembling.
