This recipe was born out of a work group chat when a colleague asked for easy work-from-home lunch ideas, says registered Nutrition Sophie Gastman (@sophiethenutritionist). “Someone threw in ‘spicy sardines on toast’ and I’ve been making my own version ever since,” she says.

“If you’re not convinced by the idea of tinned sardines, you should be. They’re cheap, last forever in the cupboard and come packed with omega-3s (plus calcium and vitamin D if you eat the little bones, which you should!).” You’ll find this high-protein recipe and loads more in her debut cookbook, Find Your Healthy – a practical guide with plenty of myth-busting. Sophie cuts through the food noise, offering evidence-based healthy eating advice alongside delicious recipes.
Healthy Tinned Sardine Recipe: Spicy Harissa Sardines and Pea-Avo Smash
This no-cook lunch is healthy, tasty and easy to throw together. Just mash tinned sardines with harissa paste and load onto sourdough along with a pea and avocado smash.
Want to… MAKE IT VEGAN? Swap the sardines for a 215g tin of (drained and rinsed) white beans or chickpeas, lightly mashed with the same garlic, harissa, lemon, coriander and pepper combo. Add a drizzle of extra virgin olive oil to make it less dry.
STORE THE LEFTOVERS? Store the leftover pea-avo smash in an airtight container in the fridge for 2-3 days. It may slightly discolour, but it will still taste fine. The sardine mix is best eaten fresh but will also keep in an airtight container in the fridge for 2-3 days.
SWAP THE TAHINI? Greek yoghurt works well, or olive oil if you want to keep it dairy-free.
SWAP THE ZA’ATAR? Dukkah, sumac or a pinch of dried oregano with sesame seeds gives a similar vibe. Or just skip it entirely.
SWAP THE SARDINES? Any tinned oily fish will work – try mackerel, salmon or even tuna.
SPEED THINGS UP? Skip the blender and just mash the peas and avocado with a fork. It’ll be a bit chunkier, but still delicious (and one less thing to clean).
