Add a tin of drained cannellini beans to the filling for extra fibre, plant protein and a more substantial meal.
These tuna melts are just as delicious served cold, Nicioise-style, stuffed into fresh capsicums without baking.
Swap capsicums for halved zucchinis or portobello mushrooms for a different low-carb twist.
Any leftover tuna mixture is perfect folded through warm pasta, spooned into lettuce cups, or layered into a sandwich or wrap.
Finish with a drizzle of sticky balsamic for the ultimate taste experience.
