Sounds really nice. Thai Green is used in this and that is a milder curry that you can spice up to your liking with the optional red Bird's Eye chilies.

I cannot price the mussels until I buy them again. The sausage might cost about 75 Baht, when I make this I will confirm the prices. For now I will say this is low cost as many times the way we get mussels is local harvested by us.
