We have got so used to buying simple sauces from the supermarket a lot of us have almost forgotten how quick and easy some of them are to make and pesto is the perfect example of that. Pop a saucepan of pasta on the hob and a pesto sauce can be made in the time the pasta takes to cook! It’s a great way to use up lots of basil but you can also switch up the sauce by swapping the basil for mint, giant Italian parsley or coriander.
