Yum Hoi Mang Pu

Ingredients:
1 cup mussel meat. (You can buy mussel meat or mussels on the half-shell- but mussel meat is far easier to work with.)
2 tablespoons fresh lemongrass, finely sliced lengthwise and in one inch strips
1/4 cup finely sliced shallots
10 Prick Kee Noo (Thai chilies) (Use flat side of a knife to flatten them so that their seeds break through the skin.)
1 head of lettuce (for the garnish)
Hand full of fresh mint leaves
2 tablespoons fish sauce
2 tablespoons lemon juice

Preparation:
1. Clean your mussels, and rinse them in water.
2. Using a small pot, bring some water to a boil, and add in the mussels. Boil them for a few minutes until done.
3. Strain the mussels, and put them aside.
4. Remove the water from the pot, and then add in all of the other items, followed by the mussels, and stir.
