GRILLED VEGETABLE PIZZA

Steps:

• The yeast: For the pizza dough, combine the yeast and warm water in a bowl of an electric mixed fitted with the paddle attachment. Stir to dissolve the yeast and allow the mixture to rest for 5 minutes.
• The dough: Using a sieve or strainer, sift about half of the flour over the yeast mixture and blend on low speed for 1 to 2 minutes. Add 1 tablespoon of the olive oil, the salt, vinegar, honey and remaining flour and mix to blend. With the mixer on medium low, mix the dough 5 to 7 minutes until it becomes a smooth ball in the bowl.
• Rest: Lightly oil a bowl with the remaining olive oil and place the dough inside. Cover with plastic wrap and let it rest in a warm place until it has doubled in volume, about 1 1/2 hours.
• The pizza rounds: Press gently on the dough and turn it onto a floured surface. Divide the dough into 4 pieces, rolling each into a loose ball. Cover with a kitchen towel and allow the dough to rest for an additional 15 minutes.
• Preheat the oven to 450 degrees F.
• Flatten each ball, then roll and gently stretch into an 8-inch round. Place each round on a pizza peel or the bottom side of a floured baking sheet.
• Prebake: Place the pizza rounds on the center racks of the oven and bake until they become firm and rigid, about 5 minutes.
• The tomato sauce: In a medium skillet, warm the olive oil, garlic and tomato paste over medium heat, stirring constantly with a wooden spoon, almost frying the paste. Add 1/2 cup water and let the tomato paste get hot and the garlic soft, 2 to 3 minutes. Add the cream, season with salt, stir and shut off the heat.
• Get ready: Preheat the grill on high.
• The vegetables: In a large bowl, combine the olive oil, red and yellow peppers, onions and red pepper flakes with a generous pinch salt.
• Grill: Lightly oil a kitchen towel with canola oil and oil the grill. Arrange the vegetables on the grill and char on all sides until tender, 8 to 10 minutes. Remove from the grill.
• The pizzas: Arrange each prebaked pizza round on the bottom of a baking sheet fitted with parchment paper or on a floured pizza peel. Arrange a quarter of the mozzarella and spoon a quarter of the sauce in a single layer on each of the pizza rounds. Leave a 1-inch edge (the crust) all around without sauce. Top with the vegetables.
• Grill: Lightly oil a kitchen towel with canola oil and oil the grill so the pizza won't stick. Slide the pizzas off the baking sheets right on to a hot (but not the hottest) part of the grill. Close the lid and cook 2 to 3 minutes to allow the dough to finish cooking and the cheese to melt. Move the pizzas gently to a less hot area and cook until browned, an additional 2 to 3 minutes.
• Finish: Transfer the pizza rounds to a serving platter. Top with the arugula leaves, lemon zest and Parmesan.
