Drain and rinse kelp noodles - make sure they are all separated. Add them to a bowl and cover with hot water. Add the baking soda and squeeze the entire lemon on top. Use your hands to massage the mixture into the noodles helping them to loosen.
In a separate bowl while the noodles soak, add all dressing ingredients to a small bowl - add more water depending on your desired consistency.
Add salad ingredients to a bowl - portion size is completely up to you. Drain and rinse kelp noodles and add to the salad. Top with dressing and sesame seeds.
