Coke Burgers for Jamie

This hamburger recipe goes out to Jamie (works for Coke) who, with his wonderful family and my favorite niece, spent the weekend with us just last week.
It is not the burgers I grilled for ya'll but sounds pretty darn tasty. Might just try it this weekend.  

Coke Burgers
1 egg
1/2 cup coca cola; divided
1/2 cup crushed saltine crackers
1/4 cup finely chopped onion
6 tablespoons creamy
French salad dressing; divided
2 tablespoons grated Parmesan cheese
1/4 teaspoon salt
1 1/2 pound ground beef
6 hamburger buns; split

In a mixing bowl, combine the egg, 1/4 cup of Coca-Cola, cracker crumbs, onion, 2 tablespoons of the dressing, cheese, and salt. Add the meat and mix well. Form into patties, 3/4-inch thick.  

For the sauce: Mix the remaining Coca-Cola and dressing. Grill the meat over medium coals about 10 minutes or to desired doneness. Turn once; baste occasionally with sauce. Serve on buns. Use remaining sauce as topping, if desired.
