Allow dough to rest for 2 to 3 minutes. Place dough in oiled bowl and allow to rise at room temperature for about 1 hour.
2. Punch dough down, divide into 2 to 4 balls, let rise another 30 minutes.

Mix both cheeses and oregano in bowl, season with salt and pepper to taste.
3. If making 4 calzones, spread 1/3 cup cheese mixture on half of each round of uncooked calzone dough, leaving 3/4-inch border. Cover cheese on each with 1/4 of onions, 1/3 cup cheese mixture, 1/4 of sausage, 1/3 cup cheese mixture, then 1/4 of bell peppers. Fold plain dough halves over filling, forming half circles.
