Have you tried to cook with arugula? And what is arugula? It is a pungent, peppery salad green also known as rocket; a member of the Brassicaceae family. It is very high in nutrition. Arugula is easy to grow in a Louisiana garden and flourishes during the winter months. That means I have a nice supply. I brought this Arugula and Penne Pasta Salad with homemade olive oil salad dressing to a pot luck dinner last week.
