Arugula and Strawberry Salad with Pumpkin Seeds and Lemon Vinaigrette

This salad was first featured in my 2009 cookbook, Easy Green Organic, so it is tried and true. Although arugula is a peppery lettuce, it's a versatile one. In Italy it is often eaten with endive and radicchio or tossed into a fresh pasta. And one of my absolute favorites.
