Mashed avocado stands in for the usual mayo here, so the tuna salad holds together and stays creamy without anything from a jar. Spoon it into whole romaine leaves and eat them like little boats.

It comes together in about ten minutes with no cooking, which makes it a good desk lunch or a fast weekend bite.

Ingredients

  • 2 cans tuna, drained
  • 1 medium avocado
  • 8 large romaine leaves
  • 2 tbsp finely diced red onion
  • 1 tbsp olive oil
  • Salt and pepper
  • 1 tbsp lemon juice
  • 1 tsp dijon mustard
  • Chopped fresh dill

Instructions

  1. 1

    Mash the avocado in a bowl with the lemon juice, dijon, olive oil, salt, and pepper until mostly smooth.

  2. 2

    Flake in the drained tuna and add the diced onion, then fold everything together.

  3. 3

    Taste and adjust the salt and lemon.

  4. 4

    Separate the romaine into whole leaves and pat them dry.

  5. 5

    Spoon the tuna into each leaf and finish with fresh dill.

Tips

  • Squeeze the tuna well before mixing so the salad does not turn watery.
