I’m not a big cheeseburger fan, to be honest. I prefer my burgers plain. But a lamb burger topped with feta? Well, that’s another matter. Ground lamb shoulder makes the tastiest burger, and crumbled feta on top contributes a creamy, briny, tangy note—like adding a sliced pickle but better. Everything else about the Fourth of July will be different this year. Why not shake up your menu, too, with these succulent burgers?
