Place the rice and coconut milk into a saucepan. Add cold water to just cover the rice. Add the lime juice and lemongrass stick.
Bring to the boil, reduce to a simmer and cook for 6-8 minutes until almost all of the liquid has been absorbed (stir occasionally to prevent the rice from catching the bottom of the pan).
Remove from the heat and cover for 15 minutes. Remove the lemongrass and discard. Add the chopped coriander and mix to combine.
For the mango salsa, place all of the ingredients into a bowl and mix well.
Serve the sticky coconut rice with a generous spoonful of mango salsa. Top with Quorn Tikka Mini Fillets and garnish with fresh coriander leaves.
