Preheat the air fryer to 375°F (190°C). In a large bowl, combine the crumbled turkey chorizo, ground chicken, breadcrumbs, salt, black pepper, minced garlic, and dried Italian herbs. Mix well until all ingredients are combined.
Shape small meatballs about the size of a teaspoon and place them in the preheated air fryer basket. Cook for 10-12 minutes, shaking halfway through, until the meatballs are browned and cooked through. Set aside.
In a large pot over medium heat, heat the olive oil. Add the chopped onion and cook until translucent, about 3-4 minutes. Add the minced garlic, celery, and carrots. Cook for a few more minutes until the vegetables are tender.
Pour the chicken broth into the pot and bring the soup to a boil. Once the soup is boiling, add the cooked meatballs directly to the pot.
Add the dry tiny pasta directly into the boiling soup, along with the chopped spinach. Cook for about 5 minutes, or until the pasta is tender and the spinach has wilted.
Taste the soup and adjust seasoning as needed with salt and pepper. Serve the hot soup in bowls and enjoy this comforting Italian wedding soup.
