I found this recipe a while back, and I've made it several times. It's definitely time for an update. The first time I made it, I followed the recipe, but I thought there was too much sauce and too much cheese, so I've modified it a bit. Yes, I know, some people don't believe there is any such thing as too much cheese, so feel free to use as much as you want.
You may not use all of the chicken or green onions. Just spread them on the pizza until it looks right to you. I only used about half of the chicken breast - it was rather large. Also, I didn't measure my green onions, sun dried tomatoes, or Parmesan cheese, just sprinkled them on until it looked good and the pizza was covered.
It's not exactly like the Papa Murphy's pizza, but it's pretty close. I especially love the garlic sauce. And there is still plenty of melty, gooey cheese on this pizza.
