One of Heidi Swanson's wonderful recipes from "Super Natural Every Day". This is a refreshing change from tomato-based sauces, with lots of layers of flavor, color (I like to use green ravioli), and texture. I also like to use twice the number of olives. Sliced and sauteed Brussels sprouts work very well in this, as does sauteed cabbage, or cauliflower florets cooked like the broccoli. Sunflower kernels or pine nuts also work instead of pepitas.
