Lemon and pecorino top off this delicious and easy homemade pizza that gets vibrant color from asparagus and artichoke. Shiso is a fuzzy-leafed herb in the mint family that's used in a variety of asian cuisines. Devoted fans grow it in their gardens; look for it at asian and farmers' markets. Note: baby artichokes hardly have chokes, so you can use a paring knife to extricate any fluff.
