Heat a large pot with olive oil on medium heat.
Add chopped onion, carrots and celery. Saute, stirring occasionally, for about 5 minutes until the veggies are softer.
Add rice and continue to cook, so the rice will absorb all the juices, about 5 more minutes.
Add veggie broth and bring to boil.
Turn the heat on low, and let it cook about 10-15 minutes or until the rice is soft.
Meanwhile, add all “egg mixture” ingredients to a food processor.
Blend until smooth and silky.
Add the “egg” mixture to the soup and stir to incorporate, add sliced tofu, green onion, and 1 tbsp dill.
Cover and let it sit 5 minutes before serving
Serve with chopped dill and lemon slices.
