Heat a heavy bottom pot on low-medium heat and warm the oil. Add the onions and cook until translucent, about 3-5 minutes
Add the chopped red bell pepper and continue cooking until soft, about another 2-4 minutes. Add the beets and balsamic vinegar; cook for an additional 5 minutes
Add 2 cups filtered water and 4 cups vegetable broth (please see recipe in note section below); turn heat up to a medium-high to bring to a boil. Reduce heat, and cook with the lid partially on until beets are cooked, about 45 minutes
Remove from the heat and stir in the zest and juice of the lemon, fresh dill, salt and pepper.
Once the soup is slightly cooled transfer it to your blender or uses an immersion blend and process until your soup is smooth in texture.
Pour Soup into bowls and if you desire top with fresh, dill and course sea salt.
