In a large bowl mix meats and all seasonings well with hands. Cover and refrigerate for at least an hour.
Heat grill, skillet or griddle.
Make 10 nice big round patties. Like u normally would for burgers.
(This is where I freeze any I won't need to make this evening) I also place a small hole in center of patty to help with puffing and shrinkage. About a small pinky size hole.)
Cook burgers like u normally would. Leaving a tad pink in center but at a safe temp.
Set burgers on a paper towel lined plate to remove excess grease (if u want to )
Warm pitas or flat buns for a few second in microwave.
Assemble burgers by spreading some tzatziki sauce on each half of flatbuns.
Place burger on one side.
Place tomato and onion on top.
Place other bun sauce side down.
Serve hot and enjoy! :)
Makes about 10 burgers depending on the size u make them.
U can add other condiments on your burger, its also good with ketchup and pickles. :)
Thanks given to bbqtvtv.com for his greek rub I used for this, also for taylor68too for her addition to the seasonings I used. And to skunkmonkey for the tzatziki sauce recipe I used for this. :)
