Make a smooth paste out of onion and garlic, with a little water if needed, set aside.
Boil chicken bones in water (half pot), until foamy. Remove the scum foam, then add in macaroni. Cook until half cooked.
Add in veggies, keep boiling until veggies half cooked, then add in green onion, followed with meat balls.
Season.
Once veggies and macaroni tender, soup is ready to serve with warm rice.
