1 box prawns with head (from an Asian store)
(basically whatever veggies you want)
1 package sinigang mix (from a Filipino store)
Boil onions, tomatoes and eggplant (if you want eggplant, you don’t have to have eggplant) with salt and water. Add prawns. When prawns are cooked, put it in a separate bowl so it does not overcook.
Add rest of vegetables.
Make sure vegetables are tender and then add sinigang mix.
You can add prawns back at this point.
Note: you can do the same with pork, ribs or beef.
