This here snack is called Thod Mun Pla, or fish cakes as I call them.
Well that's a scary shot now isn't it? I used to really dislike this snack due to the quality of the ones i ate at my place of work's canteen. They were often cold, undercooked, or poorly spiced. But after trying them on a few more occasions, I really warmed up to them. They are made by mashing up fish with chili, green beans, kaffir lime leaves, and some other spices. They're made into cakes and fried. They're served up with a sweet sauce and cucumbers. It makes a nice before, during, or after work snack.
