I've done Sinigang na hipon (prawn) and sinigang na manok (chicken) before and love both! I used the Knorr one for the prawn version and a Mama Sitas for the chicken version. Got some in the freezer and the last time I did the chicken version a couple of weeks back, I made so much that it wouldn't fit in my large wok, so had a medium saucepan and large wok full of it, with only little me to eat it all!
