To cook the pasta, bring a pan of water to the boil and add the mini conchiglie pasta shells. Cook according to packet instructions.
While the pasta is cooking, warm a little olive oil over a medium-high heat in a separate pan. Add the courgette and basil and cook quickly – the courgettes should release a little liquid, creating a sauce with the oil.
When the pasta is cooked, drain and add to the pan with the courgettes and sauce. Season well, mix until thoroughly combined and serve immediately with some grated Parmesan.
