Turkeys were never meant to trod where cattle hoofs tromp. And that fleshy wattle growing from its throat ain't no set of horns. That's why turkey burgers don't have steer power: They often lack juice and richness, and they crumble like parched bran muffins under stress. Here the burgers are juicy and rich, and they stick together like their beefy counterparts. Pesto topping and a whole-wheat muffin don't hurt any, either. It's enough to make one utter an aria of rapid gobbles.
