Slow Cooker Green Minestrone with Fennel & Parmesan
A strip of Parmesan rind in the broth gives this minestrone soup a deep, layered flavor, and fresh fennel adds a bright anise note. You don't need much pesto here—swirl in just enough to tint the broth and release its fresh-basil scent. If you avoid cheese made with rennet, look for vegetarian Parmesan cheese, which is made without it.
