Dice the onion and mince the garlic. Set aside.
To a preheated large soup pot, add 1 tablespoon extra virgin olive oil, then the ground chicken (1.5lbs). Break up the meat with a spatula or spoon. Sprinkle in ½ teaspoon of salt and ½ teaspoon of fresh ground pepper.
Stir the chicken until brown on all sides. Let it get REALLY brown on the bottom of the pan, about 5 minutes.
Before adding any other ingredients, remove about ⅓ of the browned ground meat to a separate container to store in the fridge for Pasta Bar night.
To the remaining chicken in the pot, add the diced onion, minced garlic, and Oregano. Cook stirring so that the onion and garlic don't burn, about 5 minutes.
Add the Tomato Paste and flour, then stir to mix. Then add the 5 cups broth to the pot and stir until all combined. Taste for seasoning and add salt and pepper to taste.
Partially cover so steam can escape and cook for 20 minutes, stirring every 5-7 minutes. The mixture will get thick and creamy.
If you want to bulk up this recipe even more, add some Orzo or Rice. Cook the orzo or rice separately and then mix into the soup during the last 10 minutes of cooking.
You could also just have some fresh crusty bread to dip in this soup!
