Chop the tips off both ends of the leeks and give them a rinse under the tap. Then chop up.
Slice the pepper in half, cut out the seeds and wash under the tap. Then slice each half into strips and dice.
Take a decent size saucepan, put a teaspoon of coconut oil in and place on a medium/high heat. Once heated up, put a dessert size spoon full of Thai green curry paste into the pan and leave to warm up for 30 seconds.
Next stick all the chicken into the pan and mix around so it gets a good covering of the curry paste. Once the majority of the chicken is white, put all of the veg in and stir around for a couple of second before pouring in all the coconut milk.
Leave to cook for 20 minutes and then you're done.
