Combine all ingredients together well using your hands or a mixer using the paddle attachment. The meatballs should be about the size of a large gumball. Wetting your hands will make it easier to work with.
Heat oil in a non stick frying pan
Add meatballs in batches taking care to not over crowd your pan. Brown the meatballs for about 1 minute then turn them over. They don't have to be cooked through. Repeat with remaining balls adding more oil if needed. Set aside.
*if you feel you have more meatballs then you need, you can cook them through and freeze them. Just add the frozen meatballs to your favourite soup or sauce.
For the soup:
In a large pot add oil, onion, carrot, celery, garlic and chilli flakes. Sauté on medium heat for about 10 minutes until veggies are translucent. Stir frequently as you don't want them to burn
Add chicken broth and bring to a boil then add the pasta and cook for about 8 minutes
Add Chicken meatballs and spinach and simmer covered for 15 minutes
