Sauté veggies. Heat the olive oil in a large pot over medium heat, then add onion, carrots, and celery and cook for 5–6 minutes until softened.
Add aromatics. Stir in the fresh garlic, garlic powder, onion powder, Italian seasoning, turmeric, salt, black pepper, and red pepper flakes and cook for 1 minute until fragrant.
Add broth and chicken. Pour in the chicken bone broth and water, then add the shredded chicken and bring everything to a gentle boil over medium-high heat.
Cook the pasta. Add the high-protein pasta to the pot, reduce heat to a strong simmer, and cook for 7–10 minutes (or according to package directions) until the pasta is just tender.
Finish with peas and yogurt. Stir in the frozen peas and let them heat through for 2 minutes, then turn the heat to low and whisk in the Greek yogurt until the soup looks creamy and smooth without boiling.
Add freshness and adjust. Stir in the parsley and lemon juice, taste, and adjust salt, pepper, or more water if you prefer a thinner soup.
Serve and store. Ladle into bowls and serve hot, then cool leftovers and store in the fridge for up to 4 days, adding a splash of broth or water when reheating if it thickens.
