Grilled Pizzas W Summer Squash Scallions & Ricotta

2 summer squash or zucchini (about 1 pound), thinly sliced lengthwise

2 bunches scallions

6 tablespoons olive oil, plus more for serving

Kosher salt and black pepper to taste

1 pound pizza dough, at room temperature

1 15-ounce container ricotta cheese

2 bunches arugula, thick stems removed (6 cups)

4 radishes, halved and thinly sliced

2 tablespoons red wine vinegar

Heat grill to medium heat. In a shallow baking dish or large bowl, toss the squash and scallions with 2 tablespoons of the oil, ½ teaspoon salt and 1/4 teaspoon pepper. Grill the vegetables until cooked through: 4 to 6 minutes per side for the squash, and 1 to 2 minutes per side for the scallions. Chop the scallions; return the vegetables to the dish. Stretch the dough into four 8-inch rounds. Dividing evenly, brush the dough (on both sides) with 2 tablespoons of oil. Grill the dough until puffed and cooked through, 2 to 3 minutes per side. Dividing evenly, dollop the ricotta on the pizzas and top with the grilled vegetables. In a medium bowl, toss the arugula and radishes with the vinegar, the remaining 2 tablespoons of oil, and 1/4 teaspoon each salt and pepper. Drizzle the pizzas with additional oil and serve with the salad.

Serves 4.
