To cook one serving, unwrap lasagna roll and place seam side down in microwave-safe bowl; cover with microwave-safe waxed paper. If refrigerated, microwave on HIGH for 1 to 2 minutes or until cheese begins to melt at ends of roll. Spoon 1/4 cup pasta sauce over roll; cover. Microwave on HIGH for 20 to 30 seconds or until thoroughly heated. (If frozen, microwave on LOW for 1 to 2 minutes or until thawed before heating as directed above.) Top with chopped parsley.
