Remove the salmon and jellyfish from the recipe to make it vegetarian. In fact, it will become vegan. If you still want the slippery crunch from the jellyfish you can add some shirataki konnyaku noodles. Just make sure they are nice and dry before adding them to the yee sang salad. The hoisin sauce in the yee sang sauce is vegan despite the fact that “hoisin” means “seafood”.
