Preheat a grill pan over medium
heat. In a small bowl, mash three-quarters
of the feta, the lemon peel
and 1 1/2 teaspoons olive oil.
In a medium bowl, combine the
lamb with 1/4 cup pomegranate
seeds and the remaining feta.
Shape into 4 patties. Grease the
grill pan with 1 1/2 teaspoons olive
oil, add the burgers and cook,
turning once, for 8 minutes for
medium. Transfer to a plate and
cover loosely with foil.
Meanwhile, in a bowl, toss
the arugula with the chopped
mint, the remaining 1 tablespoon
olive oil and the lemon juice;
season with salt.
Spread the bun bottoms with the
feta mixture. Press the remaining
pomegranate seeds into the cheese.
Top with the burgers, red onion,
arugula salad, whole mint leaves
and bun tops.
