Making this recipe card, as written, is out of this world! But, if you are looking to switch things up, you could use tzatziki sauce in place of the Greek aioli or swap out some of the fresh vegetables with any that you have on hand (i.e. red peppers, garbanzo beans, black olives, grape tomatoes, or fresh basil). And if you are missing that protein, feel free to add some cooked chicken breast or gyro meat to make a gyro sandwich!
