This is my favourite Thai dish of all time! I lived in Bangkok for 5 years and this was a staple of my diet. My husband and I like it very very spicy, so if you don't, cut the spice by at least half. If you prefer rice to noodles, leave them out and serve this over rice. Then it would be called "Larb Gai (Moo)". This recipe came from a Thai cooking website and has been modified slightly.
I adapted this recipe from one I found in a magazine. I lived in Thailand for 5 years and it uses all the ingredients I think of when I think of Thai food. I use a lot of chili flakes, so it ends up very spicy, so cut it down by at least half if you prefer it milder. It serves 2 hungry people or 4 if you like smaller portions. Serve over steamed Jasmine rice.
