Make your noodles. Or slice the cucumber. Or however you're doing this thing. Stick 'em in a bowl with the lemon juice, sesame oil, sesame seeds, cumin and sea salt.
Stick the bowl in the fridge for a while to let the flavours 'develop'. (Or, like me, while you cook the chicken.)
Cook the chicken. Let it cool and stick that in the fridge, too.
When you're ready to eat, served the noodles on a plate/bowl and pile the cooked chicken on top. Then throw a bit of the liquid on the top.
