Gabriela Peacock 14-day plan: Seared sesame tuna with green beans & carrots

Tuna is quite a meaty fish, so it can be a good replacement for red meat, which should be eaten sparingly. It is also very high in selenium, a natural antioxidant, and along with the crunchy sesame seeds is an excellent source of essential fatty acids.

GLUTEN-FREE (if using tamari)


1 tuna steak (about 100g)
1 tsp sesame seeds
1 tsp rapeseed oil
120g green beans, topped and tailed
1 small carrot, grated or spiralised
1 tsp tamari or soy sauce
Juice of 1⁄2 lime

  1. Season and coat the tuna steak in the sesame seeds, pressing them in gently so they stick.
  2. Heat half the oil in a frying pan over a medium heat then add the beans, along with a splash of water, and cook for a couple of minutes.
  3. Next add the carrot and cook for a further minute before adding the tamari or soy sauce and stirring well. Remove from the heat (the vegetables should still have a bite to them) and transfer to a plate.
  4. Using the same pan, heat the rest of the oil and sear the tuna for a minute or two on each side (this will depend on the thickness of the fish and how rare you like it).
  5. Place the tuna on top of the crunchy vegetables and squeeze over the lime juice before serving.
