Tuna & Avocado Tartine

This tuna and avocado tartine is just a post name for a simple, nutritious and tasty open-faced sandwich.

You can mix the avocado with whatever ingredients you have available but here I’ve used tuna.

Avocados are a great source of monounsaturated fat, fibre and many other beneficial vitamins and minerals. However, they are low in protein so adding a little tuna helps to balance that out. 

Top tips:

  • Opt for canned tuna in spring water where possible to avoid any added salt.
  • I recommend using wholemeal bread as it’s higher in fibre, and young children don’t tend to eat enough fibre.
  • You could replace the cherry tomatoes with grated carrot, sliced cucumber, and maybe some diced red pepper.
  • You can also replace the lemon juice with lime juice if you prefer, or leave it out entirely.
