This sauce is a really delicious way of using a glut of courgettes. But no glut necessary! If you are looking for a really simple and quick dinner give this one a go.
You could also cook the pasta in the Instant Pot. In which case, make the sauce, set aside then cook the pasta. Once the pasta is done, drain and return to the instant pot and stir in the sauce. The residual heat of the pasta and the pot will reheat the sauce sufficiently.
