This is what I like to call working [wo]man's pizza. It's the kind of dinner that comes together in minutes for an easy, effortless weeknight meal. The addition of fresh arugula and basil gives the pizza a certain garden-fresh quality while the three cheeses add an additional layer of indulgence. Use the topping suggestions as a guideline. Experiment. Create your own variation based upon the odds and ends left in your fridge at the end of the week. Who doesn't love a a good fridge clean out meal? I know this frugalish gal does!
One final word on the crust from the test kitchen: leave the pizza in the oven longer than you think it should. A deeply browned crust is the key to turning this tortilla crust into a wood-fired thin-crust-like taste. Trust me. I learned through trial and error... See the photo below - that's the crust color you're looking for.
