Preheat a big pot over medium heat with some sesame oil.
When warm add the shallots, galic cloved, ginger and red chili to the pot and fry for 1-2 minutes, until it starts to get soft and golden brown.
Next add the lemongrass, stock cube and water to the pot and bring to a boil.
Reduce the heat and let the soup cook for 40-45 minutes.
Add the tamari, rince vinegar and lime juice to the soup. Taste to check if more is needed.
Add the scampi and prawns and let the soup cook for 1-2 minutes, not longer. You don't want the scampi and prawns to be over cooked.
Add the gluten free soba noodles and let them cook for 1 minutes, stirring regularly.
Divide the soup between bowls.
Top with red chili, scallion, sesame seeds and cilantro.
