5. 2 x 220g packs ready- cooked pasta (we used Dolmio Express), or 440g leftover cooked penne (about 200g dried) 100g can tuna in oil 400g can cannellini beans, (borlotti or butterbeans are also good) 1⁄2 red onion, finely chopped zest and juice 1 lemon large handful parsley

6. Microwave the cooked penne according to pack instructions. Tip into a bowl. Mix through the remaining ingredients (the warm pasta will really soak up the flavours). If using chilled leftover pasta, simply mix everything together - it will still taste great. Can be kept in the fridge for up to 3 days.
