Cook the pasta according to package instructions. Cut the chorizo in thin slices and bake them in a frying pan until crunchy. Add the chopped garlic and bake for another minute. Take of the heat and set aside.
In another pan ad the oliveoil and bake the courgette. Add the peas and bake those quickly as well.
Drain the pasta and keep some of the cooking water
Add the pasta to the courgette and add a few tablespoons of the cooking liquid with the juice and zest of the lemon. Add the chorizo and eat with loads of parmesan (or non. Tom doesn't do the cheese thing and still liked it a lot)
