LAMB BURGERS

Steps:

• Coat a large saute pan with olive oil, toss in the diced onions and season with salt and crushed red pepper. Bring the pan to medium-high heat and cook the onions for 3 to 4 minutes. Add the garlic and cook for 2 to 4 more minutes. Turn the heat off and let cool.
• In a large bowl, combine the lamb, the cooled onion mixture, the dill, mint, oregano, lemon zest and 1/2 to 3/4 cup water. Sprinkle with salt and combine well. Make a little "tester patty," cook it and taste for seasoning.
• Preheat the grill.
• Form the lamb mixture into 4 equal patties and sprinkle with salt. Grill the burgers to your desired doneness, 4 to 5 minutes per side for medium-rare. Remove the burgers from the grill and let rest for 3 to 4 minutes.
• Cut the Whole-Wheat Pitas in half. Schmear each half generously with the Pickled Feta Spread. Top one half with a burger, then tomatoes, sliced onions and spinach. Place the other pita half on top.
• In a small bowl, combine the warm water, sugar and yeast and let sit for 15 minutes.
• In the bowl of a stand mixer, combine the flours, cumin, salt and cayenne. Add the yeast mixture and the olive oil. Mix on medium speed to combine and knead the dough. It should take 6 to 7 minutes. The dough will be firm and not sticky or tacky.
• Place the dough in a lightly oiled mixing bowl, cover with plastic wrap and let rise in a warm place until the dough has doubled in size, about 1 1/2 hours.
• Preheat the oven to 500 degrees F.
• Divide the dough into 8 equal pieces and roll into 7-inch rounds (1/4-inch thick). Divide the dough between 2 sheet trays, cover them loosely with a clean tea towel or plastic wrap and let rest for 20 minutes.
• Bake the pitas for 3 to 4 minutes, then turn the pitas over and bake for 2 more minutes. Let cool and use as desired.
• Place the vinegar, sugar, salt, tea bags, bay leaf and herb stems, if using, in a small saucepan along with 1 cup water. Heat until the sugar and salt has dissolved. Remove from the heat and let cool.
• Place the feta in a small container. Add the vinegar mixture and be sure that the feta is submerged in the liquid. Let sit for a couple of hours outside the refrigerator if using right away, or in the refrigerator if using in the future.
• Strain the feta from the pickling liquid and discard the tea bags, bay leaf and stems. Place the feta in a food processor and add the yogurt. Pulse until combined.
