      Nutritionist's tip

      While there's some types of fish you should definitely avoid in pregnancy2, tuna can be eaten in moderation. However, since tuna contains more mercury than other types of fish, you should limit the amount of tuna you eat to no more than two tuna steaks a week or four medium-sized cans of tuna a week when pregnant. The amount of mercury we get from food isn't harmful to most people but it could affect your baby's developing nervous system if you have too much in pregnancy2.

      1. Put the quinoa on to cook according to the packet instructions.
      2. To prepare the salad dressing, simply put the ingredients along with a little salt and pepper in a screw top jar, secure the lid and shake vigorously.
      3. Scatter the sesame seeds on a large plate along with a fair amount of pepper and then dip the tuna steaks in so that they are evenly coated all over.
      4. Divide the oil between two large frying pans over a medium heat. If you only have one large pan, then cook the tuna in two batches rather than squish all four in and stew them!
      5. Cook the tuna steaks for around 2-3 minutes per side for a medium-rare finish, depending on the thickness of your steaks (it’s fine to eat partly cooked tuna in pregnancy if it’s been frozen and fully defrosted first8). Of course, you can cook your tuna steaks for longer if you prefer. Remove and set aside.
      6. Once cooked, rinse the quinoa under cold running water and set aside to cool down completely. Once cooled, toss it in a large serving bowl with the mango and spinach and season to taste.
      7. Divide the salad among four serving plates (or four lunch box containers). Place a piece of fish over each salad and then drizzle over the dressing.
