Food is an important item in space , not only to give your body the nutrients its needs but also to help your mental well-being too.
That's why astronauts are allowed a certain amount of "bonus foods" of their choice that reminds them of things they would back on Earth.
Whilst on the ISS, Samantha showed us how she manages to cook one of her bonus food recipes in microgravity: a quinoa salad with dried tomatoes, mackerel and leek cream, all wrapped in a warm tortilla.
