Add sliced onion, carrots, garlic, salt, pepper, turmeric, and juice from 1 of the lemons.
Pour in the chicken broth. Cover, and cook on high for 2 hours.
Shred the chicken and return it to the crock pot.
Add ditalini, spinach, juice from the second lemon, and the dill.
Stir and cover. Cook for 30 minutes.
Serve warm, garnished with dill and lemon slices.
Notes
Use fresh lemon juice: It makes a big difference in brightness. Don’t overcook the pasta: Add it toward the end so it stays tender. Shred chicken with forks: It pulls apart easily when cooked fully. Stir before serving: The pasta and spinach need a good mix before ladling.
