Bring a medium sized saucepan of salted water to the boil and blanch the broccolini and carrot slices for a couple of minutes. Transfer them to a sieve to steam dry, and blanch the pak choi extremely quickly – ideally the leaves will remain firm.
Preheat the oven to 180C/356F and spray a 27cm oval baking dish with oil.
Using a large bowl, whisk the eggs vigorously until the whites have broken down.
Add the remaining ingredients for the frittata, and continue to whisk until the curry paste is completely incorporated.
Arrange 3/4 of the vegetables in your baking tin (reserving some to decorate) – I used a 27cm oval Le Creuset.
Once the vegetables are arranged, pour the frittata mixture over the top, and finish with the remaining decorative vegetables. Give the top a good spray with oil to prevent the vegetables from burning.Place the frittata in the oven for 35-45 minutes, or until it has completely set and the top is lovely and brown. I like to finish mine under the grill for a few minutes.Remove from the oven and serve with remaining Thai basil, toasted coconut flakes, chilli, and, if you’re feeling fancy, a squeeze of lime juice.
