Pizza on the grill! I found this recipe a couple months ago while searching for a potato pizza recipe on Google. It is from a personal blog that includes a food section http://www.invisible-jet.net and is attributed to "Mia." I have made it once with a prepared wheat pizza dough, baking it instead of grilling it, and it was very tasty though a little greasy. The carmelized onions and Raclette (a mild, nutty semi-firm cheese from Switzerland), not to mention the fresh lemon juice, are really what make it interesting, and I imagine grilling it only serves to enhance the taste further. I read that Gruyere, Emmental, Jarlsberg or Swiss cheese are good substitutes for Raclette. An unusual, rich and satisfying pizza. Prep time does not include the time spent making the pizza dough.
