Place rice in a small dry skillet. Roast over medium heat until fragrant and golden brown, about 10 minutes, shaking occasionally. Transfer to a plate or bowl to cool. When cool, place in a mortar or spice grinder, and grind until it is the consistency of coarse sand.
Heat the oil in a non-stick skillet or wok over high heat. Add turkey and break up with a wooden spoon. Cook until turkey is well browned, about 10 minutes. Transfer to a bowl to cool.
Add all remaining ingredients to turkey and stir to combine. Serve immediately, lukewarm. Serve on top of lettuce or cabbage leaves if you wish, with rice on the side.
Notes
This dish is traditionally made quite spicy, but 1/2 tsp chili flakes makes it only mildly spicy. If you prefer hotter, add more chili flakes and/or hot pepper.
