Back where I came from, when one wants to fill up mid day, we have a vast option of savoury to munch on such as curry puffs, cucur udang, yam cake, roti canai, fish ball sticks etc, etc. Even salty cream cracker which is so difficult to find here in Germany but can be found all over in England.
Over here, it is mostly sweet stuffs such as biscuits, chocolates and cakes. I don´t mind sweet stuff but I am one of the unfortunate one to have to be very careful of sugar intake. So, its great when I get my fix of savoury snacks with these.
