Ingredients
  

For the low FODMAP nut free pesto (makes enough for 2 sandwiches):

  • 50 g basil leaves 1 large bunch with stems removed
  • 25-50 g finely and freshly grated parmesan to your tastes
  • 40-60 ml 2-3 tablespoons olive oil
  • Lemon juice to your tastes
  • Seasoning to your tastes

For the tuna mixture:

  • 1 X 185g can chilli tuna drained
  • 1 tablespoon mayonnaise or to your tastes
  • 2 teaspoons capers or to your tastes
  • ½ - 1 teaspoon Dijon mustard or to your tastes
  • 1 tablespoon fresh dill or to your tastes
  • 1 teaspoon maple syrup or to your tastes

For the sandwich:

  • 3 slices common tomato (40-50g)
  • ¼ avocado thinly sliced
  • Handful of rocket/arugula roughly torn
  • Seasoning to your tastes
  • 2 thick cut slices of gluten free bread toasted

Instructions
 

  • Make the pesto in a small blender or by hand. Taste and adjust according to your preferences. Once you’re happy, set aside. If you are making it in advance, decant into a small tub and pour a thin layer of oil over to top to stop oxidisation.
  • Combine the ingredients for the tuna mixture in a small blender. Blitz until smooth and mousse like in texture. Taste and adjust according to your preferences. It can be helpful to chill the tuna mixture prior to use so that it firms up a little.
  • Toast your slices of bread. Spread a generous amount of pesto on one side and the tuna mixture on the other side.
  • Top the pesto side with the sliced tomatoes, sliced avocado, seasoning and pickled onion. Top the tuna side with the torn rocket.
  • Sandwich the pieces together and serve! I like to cut mine in half because it is a very full sandwich. Best served while the bread is warm.
