In a bowl, combine the tomato sauce, crushed tomatoes, sugar, lemon juice (or vinegar), oregano, basil, garlic powder, onion powder, salt, and pepper. Stir until well mixed.
Pour Sauce Over Rolls:
Pour the sauce evenly over the stuffed cabbage rolls in the baking dish.
Step 5: Bake
Cover and Bake:
Cover the baking dish with aluminum foil. Bake in the preheated oven for 1.5 to 2 hours, or until the cabbage is tender and the filling is cooked through.
Remove Foil:
About 15 minutes before the rolls are done, remove the foil to allow the tops to brown slightly.
Step 6: Serve
Garnish and Enjoy:
Remove the cabbage rolls from the oven and let them cool slightly before serving. Garnish with fresh parsley if desired. Serve with extra sauce from the baking dish.
