1In a pot, combine water, chicken, tamarind, tomatoes, and onion. Bring to a boil and simmer until chicken is tender.
2Add string beans and eggplant. Season with salt and pepper. Simmer for another 5-10 minutes.
3Adjust seasoning if needed. Serve hot with steamed rice.
For a richer flavor, you can add dahon ng sili (chili leaves) during the last few minutes of cooking. Adjust the amount of tamarind based on your preferred level of sourness.
