Boil water in a saucepan.
Cut the zucchini into half-moons and plunge 2/3 into it in the saucepan.
Mix the basil, parmesan, a drizzle of olive oil and the remaining 1/3 of the courgettes to obtain the sauce.
Drain and reserve the courgettes and plunge the fusilloni into the saucepan with the same water.
Finish cooking the zucchini (keep a handful for dressing) in a pan, turn off the heat and add the pasta and sauce, add parmesan and mix.
Arrange in a large bowl and add the handful of zucchini, parmesan shavings, a few sunflower seeds and small basil leaves and voila!
