The fun part of pizza making is getting creative with toppings, using whatever we have in the house. We have been putting hummus on our pizza crust for quite some time. On top of the hummus, you can put any greens you have. Sometimes I use watercress or baby spinach for the kids because they are milder, though I love to use fresh spring baby arugula. The sautéed mushrooms add a great texture and pop of flavor.
