In a 15x10x1-inch baking pan, combine eggplant, zucchini, sweet pepper, mushrooms, and onion. Drizzle with oil; toss gently to coat. Roast on the center oven rack, uncovered, for 15 to 18 minutes or until tender, stirring once. Cool slightly. For filling, in a large bowl combine roasted vegetables, walnuts, rosemary, salt, and black pepper. Add cheese; toss gently to combine. On a lightly floured surface, roll one portion of Pizza Dough into a 13x10-inch oval. Spread half of the filling crosswise over half of the oval, leaving a 1-inch border. Fold dough over filling; pinch edges together to seal. Cut a few slits in top of calzone to allow steam to escape. Brush lightly with milk. Sprinkle a baking sheet or pizza peel with cornmeal. Place calzone on baking sheet or peel. (When the baking sheet or peel is moved back and forth, the calzone should move freely.) Use the baking sheet or peel to transfer calzone to preheated baking stone. Bake for 12 to 18 minutes or until golden brown. Use the baking sheet or peel to transfer calzone to a cutting board. Repeat with the remaining dough and filling. To serve, cut each calzone into thirds. Pizza Dough In a small bowl combine warm water, oil, yeast, and sugar, stirring to dissolve yeast. Let stand about 10 minutes or until foamy. Meanwhile, in a medium bowl combine 1 cup of the flour and the salt. Stir yeast mixture into flour mixture until smooth. Stir in as much of the remaining flour as you can. Turn dough out onto a lightly floured surface. Knead in enough of the remaining flour to make a moderately soft dough that is smooth but just slightly sticky (3 to 5 minutes total). Shape dough into a ball. Place in a lightly greased bowl, turning once to grease surface. Cover and let rise in a warm place until double in size (about 45 minutes). Punch dough down. Turn out onto a lightly floured surface. Divide in half. Cover and let rest for 10 minutes. Use as directed in individual recipes. *Tip: If you don't have a baking stone, place the calzone on a baking sheet sprinkled with cornmeal. Bake as directed.
