As a child, I always assumed that traditional pesto contained feta cheese, milk, and a hearty amount of spinach.  However, it wouldn't be until I began culinary school that I learned that my mom's traditional pesto was actually a Peruvian version common in most, if not all, Peruvian restaurants.

In this recipe, I marry both the Italian and Peruvian versions to give a creamy yet hearty sauce. The creaminess comes from the addition of evaporated milk, which has a mouthfeel similar to cream, but not as heavy. Walnuts replace the Italian pine nuts to provide texture as well as healthy omega-3s, and their nuttiness pairs nicely with the pecorino Romano.

As for the feta, it provides the saltiness that completes the whole dish. Feel free to try other cheeses such as goat cheese and queso fresco, a Latin cheese that is similar to feta, but not as prominent. The cherry tomatoes provide a sweet and tart flavor, and their color makes this an eye-catching side dish.  To complete the meal, serve along with grilled chicken or rack of lamb to wow your guests. Enjoy!
