Description

This viral Tunacado recipe is a copycat of Joe & The Juice’s famous sandwich — a creamy, high-protein blend of tuna mousse, ripe avocado, and zesty pesto on thin, crispy flatbread. Quick to make, easy to customize, and perfect for lunch or meal prep!


Ingredients

Scale

For the Tuna Mousse:

  • 1 (5 oz) can tuna in water, drained

  • 1½ tbsp mayonnaise (or Greek yogurt)

  • 1 tsp Dijon mustard (optional)

  • 1 tsp lemon juice

  • Pinch of salt & pepper

  • 1 tsp capers (optional)

Sandwich Assembly:

  • 2 slices thin sourdough or flatbread

  • ¼ ripe avocado, thinly sliced

  • 1 tbsp basil pesto

  • Optional: chili flakes, pickled onions, sprouts, olive oil spray


Instructions

  1. Make the Tuna Mousse:
    In a bowl, combine tuna, mayo (or yogurt), mustard, lemon juice, salt, and capers. Mix until smooth using a fork or immersion blender.

  2. Toast the Bread:
    Toast only the inside of your bread in a hot skillet or sandwich press until lightly golden.

  3. Assemble the Sandwich:
    Spread pesto on the toasted side of one slice. Layer with tuna mousse, avocado, and any optional toppings. Top with the second slice (toasted side in).

  4. Finish & Serve:
    Press gently, slice diagonally, and serve warm or chilled. Enjoy!

Notes

  • Vegan option: Use chickpeas instead of tuna, vegan mayo, and dairy-free pesto.

  • High-protein tip: Swap mayo for Greek yogurt and use sprouted grain bread.

  • Meal prep: Store tuna mousse separately and assemble fresh to avoid sogginess.
