Personally, I would lose the oil in the marinate and serve this on a bed of lettuce.
Lemon or thai basil would also be a wonderful garnish with the Goi Tom.
Both are cheap and easy to grow.

I’ve tried Vietnamese several times. I just didn’t care for it. I love Thai though, which is why I thought I’d like Vietnamese. :(
