The recipe for the CPK Roasted Garlic Chicken pizza does not appear in the version of the CPK Cookbook I have, but if you look at what is used on that pizza, at
http://www.cpk.com/menu/pdfs/menu.pdf, you will see that the pizza features "Roasted garlic, grilled chicken, Mozzarella cheese, mild onions and fresh Italian parsley with a white wine and garlic-shallot butter sauce". If I were you, I think I would use a related recipe for the CPK Rosemary Chicken and Potato Pizza, at
http://www.recipesource.com/main-dishes/pizza/rosemary-chicken-potato1.html, but leave out the potatoes, most or all of the rosemary, and the oregano, and add roasted garlic cloves and onions (with more onions by weight than roasted garlic). My guess is that CPK uses common ingredients for the two types of pizzas since it makes good business sense to do so. When I have made the Garlic-Shallot Butter with Lemon sauce for the CPK potato/rosemary chicken recipe, I used chardonnay wine, but if you look at the frozen version of the Roasted Garlic Chicken Pizza, at
http://frozen.cpk.com/CT-garlic-chicken.html, you will see that chablis is used for the frozen version. It's up to you to decide on which wine to use, but either should work quite well. If you strip away all of the sub-components of the frozen version of the Roasted Garlic Pizza, I believe you end up with something like the following:
WHEAT FLOUR, SHREDDED LOW-MOISTURE PART-SKIM MOZZARELLA CHEESE, WATER, COOKED WHITE CHICKEN MEAT, BORDELAISE BUTTER SAUCE, ONIONS, ROASTED GARLIC (GARLIC, CANOLA OIL), SUGAR, SOYBEAN OIL, CONTAINS LESS THAN 2% OF WHEAT GLUTEN, SALT, YEAST.I believe that the wheat flour, water, sugar, soybean oil, wheat gluten, salt (part of the total) and yeast are the dough ingredients. So, the rest of the ingredients are what you should be trying to recreate. If the frozen version of the pizza tracks the ones sold in the CPK stores, then you could use the same pecking order of ingredients by weight for the cheese, chicken, Bordelaise sauce, onions and roasted garlic.
However you decide to proceed, please let us know how things turn out, including photos if possible.
