Put the meat in a large mixing bowl that will hold all the ingredients. Add fish sauce, shallot, green onion, the rest of the lime juice, hot peppers or red chili pepper flakes and almost all of toasted rice/sesame seeds into the bowl. Save some toasted rice/sesame seeds to sprinkle on top for garnish. Mix well and taste. It should be a little bit hot. If you want it hotter, add more chile flakes. You should be able to taste tartness from the lime juice and the fish sauce. If you need to add more fish sauce or lime juice, don't be afraid. Taste test to make sure your larb is balanced the way you like it.
