Heat half the oil in a large non-stick frying pan and fry the turkey mince for 3 - 5 minutes until golden; break up with a wooden spoon as it cooks. Remove the turkey and set it aside.
In the same pan, add the remaining oil and fry the onion until soft; add mushrooms and continue to cook until golden; then stir in grated carrot, on-ion salt, cumin, chilli flakes, and continue to cook for 2 minutes.
Return the turkey mince to the pan, add half the chopped mint and season.
Arrange lettuce cups onto a large serving plate, fill the cups with turkey mix-ture and scallions, drizzle with yoghurt, honey, and peanut rayu and sprinkle with remaining mint. Serve immediately.
