Our spinach and walnut pesto pasta is a delicious vegetarian meal that the whole family can enjoy together.
This is one of our favourite healthy family meals. As well as tasting great and being packed with fibre, walnuts are significantly higher in omega-3 fat than any other nut. As a bonus, this recipe uses pecorino, which is made from sheep’s milk and is higher in omega 3 than Parmesan.

Method
- Toast the walnuts in a small frying pan for 5 minutes, shaking occasionally until golden. Set aside to cool.
- Cook the spaghetti in a large pan of boiling water, according to the pack instructions, adding the green beans for the last 3 minutes of cooking.
- Meanwhile, put the cooled walnuts, garlic, lemon zest and chilli flakes in a food processor and whizz until finely chopped. Add 2 large handfuls of spinach plus the basil, and whizz again. Add the lemon juice, oil and cheese, plus a ladleful of cooking water from the pasta pan, and blend again to make a fairly smooth pesto.
- Drain the pasta and beans, reserving a mug of the water, then return to the pan. Stir in the remaining spinach leaves and the pesto, adding a splash of the reserved water if needed.
- Divide the spaghetti between 4 bowls, and sprinkle over a little extra cheese and a good grinding of black pepper before serving.

A traditional pesto is made with basil leaves which gives a beautiful, vibrant green colour. There is usually no spinach in a peso recipe but adding a couple of handfuls is an excellent way to get a boost of nutrients and it adds an interesting flavour too.
"Pesto is a great way to add extra veggies into everyone's diet without them knowing there is added veg content. You could add a handful of peas to this pesto for some extra goodness and a little sweetness. Omit the chilli if cooking for little children and sprinkle over the adult portions when serving instead."
