# Steps to Follow:

01 - Bring chicken stock to a gentle boil in a large saucepan. Add lemongrass, kaffir lime leaves, galangal, and smashed chiles. Simmer for 5 minutes to infuse flavors into the broth.
02 - Add sliced chicken to the simmering broth. Cook for 3-4 minutes until just cooked through. Skim off any foam that rises to the surface.
03 - Stir in mushrooms, tomatoes, and onion. Simmer for 3-4 minutes until vegetables are tender-crisp, avoiding overcooking.
04 - Add nam prik pao, fish sauce, sugar, and salt. Stir thoroughly to incorporate the chili paste. Simmer for 2 minutes. Taste and adjust seasoning as needed.
05 - Remove from heat. Stir in fresh lime juice. Taste again and adjust sourness or salt levels to achieve the signature sweet-sour-spicy balance.
06 - Ladle hot soup into serving bowls. Top with chopped fresh cilantro and sliced Thai chiles if desired. Accompany with lime wedges for additional seasoning.
