The Modern Nonna

0 Add the water and vegetable broth to a large pot. Add the shallots, celery, carrot, garlic, and bell pepper (if using) and bring to a boil. Once boiling, add 1/2 tablespoon salt. 
1 Reduce the heat to medium-low and partially cover the pot with a lid. Let the broth simmer for 25 to 30 minutes or until all the veggies are super soft. Taste the broth for salt and adjust as needed. 
4 In the meantime, combine the ground meat, egg, onion, breadcrumbs, salt, paprika, and oregano in a bowl. Using a large spoon or clean hands, combine the mixture really well. Using a mini ice cream scoop or a spoon, form the mixture into small meatballs. It helps to oil your hands (or wet them) to form smooth meatballs and prevent the mixture from sticking to your hands. Transfer the meatballs to a plate. 
2 Using a slotted spoon, transfer the whole veggies from the broth and into a blender (see safety reminder below). Add 2 ladles of broth to the blender and blend until nice and smooth. Return the blended mixture to the broth in the pot. 
3 Bring the soup to a boil and slowly add in the mini meatballs as you gently stir the soup. Add the rice and reduce the heat to medium, allowing the meatballs and rice to cook for about 15 minutes. 
7 Once the rice and meatballs have cooked (taste the rice for doneness), taste for salt and adjust accordingly. If the rice has absorbed too much broth, add a little bit of water to thin out the soup. Remove the soup from the heat and garnish with fresh parsley. Squeeze some lemon into each bowl and enjoy! 
SAFETY REMINDER
8 Hot soup (or any hot liquid, for that matter) will steam and expand in a stand blender, which can push the lid of the blender off and cause a mess and burn hazard. When pureeing hot soup, do it in batches. Fill the blender 1/3 to 1/2 full, remove or loosen the center cap from the lid of the blender. Cover the lid with a folded dishcloth and hold it down while blending.
