Sausage and Red Pepper Calzones

1 teaspoon olive oil
2 cups thinly sliced red bell pepper (about 2)
1 cup chopped onion (about 1)
2 garlic cloves, minced
1 pound chicken apple sausage (such as Gerhard's), cut into 1/4-inch slices
3/4 cup (3 ounces) shredded part-skim mozzarella cheese
1/2 cup no-salt-added tomato sauce
1/4 cup 2% low-fat cottage cheese
2 tablespoons grated fresh Parmesan cheese
1 teaspoon dried oregano
1/2 teaspoon kosher salt
1/4 teaspoon crushed red pepper

Preparation
I USE A PACKAGED PIZZA CRUST RECIPE FOR THE OUTSIDE SO DISREGARD EVERYTHING UNTIL “To prepare filling”.
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°. 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.
