Used different ingredients.
These burgers were scrumptious! I'd take them any day over regular hamburgers! (The husband, who's a big turkey fan, adored them too). When I made them, I substituted onion powder for chopped onion, left out the garlic, and added a few tablespoons of soy sauce, a couple teaspoons of worchestershire, and a few shakes of hot sauce. I also used seasoning salt instead of regular salt. And I used italian-style bread crumbs. I put these on the grill, and sprinkled a little garlic powder and a little more worchestershire sauce on them as they cooked. I served them topped with lettuce, red onion, tomato sauce, and mustard, and they were so flavourful and juicy! Some other users said they added mushrooms to keep the burgers from being dry, but i found that the worchestershire will do the job just fine, and adds better flavour!
