The Greek Burger

By Natalina Koropoulos of Mourayo

1 pound ground lamb
1 pound ground beef
1 tablespoon chopped shallots
4 teaspoons chopped fresh mint
1/3 of a cucumber, grated with the skin on, then drained in a cheesecloth
2 cloves garlic, finely chopped
1 teaspoon chopped fresh dill
1 cup Greek yogurt
2 tomatoes, sliced
1/3 red onion, sliced
1 teaspoon fresh oregano
1 teaspoon olive oil
Salt and pepper to taste
1 cup feta cheese, crumbled
4 rounds pita bread, brushed with olive oil, sprinkled with oregano, and toasted or grilled

In a bowl, mix the lamb, beef, shallots, and mint until just combined. Season to taste with salt and pepper. Divide into 4 patties.

Preheat the grill to a medium-high flame and cook the burgers to desired temperature.

Make a tzatziki by combining the cucumber, garlic, dill, and yogurt.

In a separate bowl, toss the tomato, red onion, oregano, and olive oil. Season to taste with salt and pepper.

Spread each pita round with tzatziki and top with a burger, the tomato-onion mixture, and feta.
