Drizzle a little pesto onto your bowl of soup to add pizzazz.

Its also great as a dip for bread, a nice alternative to butter or olive oil.

Because pesto lends itself well to substitutions, it is a wonderfully versatile sauce.

Dont have basil on hand?

Put those carrot top stems to good use.

This peppery green is a great replacement for basil.

Flat-leaf parsley can also be used in place of basil.

As mentioned, pine nuts, which are often rather expensive, arent mandatory either.

Use a more affordable nut alternative like walnuts or skip the nuts altogether and make theFrench version, pistou.

Parmesan cheese may be the classic standby but its certainly not the only option.
