Preheat oven to 425 (or preheat grill to medium heat)
Roll out the pizza dough into a circle - when the pizza is almost 12 inches make four 1/2 in cuts around the outer edge to create the 3 leaves and step of the clover. Press the points of the cut back into the dough and roll out a little more to get the right shape.
prick with a fork all over and prebake 5-6 mins
spread the sauce onto the dough, it should cover it completely but be thin.
Now spread the toppings over the top - I start with the chicken, onion and garlic mixture, then add the mushrooms, spinach,artichoke hearts and bacon bits
Top with a thin layer of the cheese (you don't need to use it all)
Put it back in the oven and bake another 5-6 mins, until the edges and cheese are golden
I actually like to pre-bake the pizza dough circles for 6 mins - THEN add the toppings and bake another 6 mins. The reason I do this is I don't want to dry out the already baked chicken or other ingredients or over bake the cheese. Or of course under bake the crust while trying not to over bake the toppings. Just a personal preference!
