Line a 13x9x2" pan with aluminum foil (since we are going to put this in the broiler later, don't use parchment paper!) and rub with oilve oil. Set aside.
Mix egg whites and olive oil until combined.
Add remaining crust ingredients, and mix well.
Pour crust batter into pan, and bake for 16-18 minutes, just until firm. To avoid having a dry bread crust, do not overbake!
Remove from oven, and let cool enough so that you can handle the foil and remove it from the pan (with the crust on it).
Place on broiler tray, and wipe off any extra olive oil that may be on the exposed foil.
Top crust with sauce, basil and garlic, Locatelli cheese, and mozzarella cheese.
Place in broiler for a minute or two, just until the cheese is melted.
Remove from broiler, slice, and enjoy!
Notes
In case I wasn't clear about this above: for best results, use good sauce and good cheese. That's what is going to make it taste like pizza, so don't skimp! :)
