These burgers are very healthy and have a bright, piquant flavor. I'm not a big fan of beef, and my husband would eat a cow a day if he could, but I make these and we're both happy. The amounts of cilantro, garlic, and lemon zest are very flexible. Also, the burgers are great by themselves with a little mustard on bread, if you don't want to shred cabbage, but the toppings all really pull it together and make it a favorite around here. This recipe will make 2-3 large or 4 smallish burgers.
