Coat your fingertips with flour as you crimp the calzones to prevent the dough from sticking. Use mild Italian chicken sausage, if desired.
8 servings (serving size: 1 calzone)
To prepare dough, lightly spoon flour into dry measuring cups; level with a knife. Combine 1/2 cup flour, 1 cup warm water, yeast, and sugar in a large bowl; let stand 15 minutes. Gradually add 1 3/4 cups flour, 1 tablespoon oil, and 3/4 teaspoon salt; stir until a soft dough forms. Knead until smooth and elastic (about 8 minutes); add enough of remaining 1/2 cup flour, 1 tablespoon at a time, to prevent dough from sticking to hands.
Place dough in a large bowl coated with cooking spray, turning to coat top. Cover and let rise in a warm place (85°), free from drafts, 1 hour or until doubled in size. (Gently press two fingers into dough. If indentation remains, dough has risen enough.)
To prepare filling, heat 1 teaspoon oil over medium-high heat in a large nonstick skillet. Add bell pepper, onion, garlic, and sausage; sauté 10 minutes or until tender. Spoon mixture into a bowl; cool slightly. Add mozzarella and remaining ingredients to sausage mixture; stir well.
Preheat oven to 450°.
Punch dough down; cover and let rest 5 minutes. Divide into 8 equal portions. Roll each portion into a 6-inch circle on a lightly floured surface. Spoon about 1/2 cup sausage mixture onto half of each circle, leaving a 1/2-inch border. Fold dough over filling; crimp edges of dough with fingers to seal. Place calzones on a large baking sheet lined with foil and coated with cooking spray. Pierce the tops of the dough once with a fork. Lightly coat the calzones with cooking spray. Bake at 450° for 14 minutes or until browned. Remove from oven. Cool completely on a wire rack.
Coat a sheet of foil with cooking spray. Place 1 calzone on coated side of foil; seal. Repeat procedure with remaining calzones and cooking spray. Place calzones in a heavy-duty zip-top plastic bag; freeze.
Preheat oven to 450°.
To reheat, place foil-wrapped, frozen calzones on a large baking sheet. Bake at 450° for 40 minutes or until thoroughly heated.
