Falafel Pitas with Yogurt Sauce

• In a small bowl, combine the white wine vinegar with the sugar, then add half of the onion (see Tip). 
• Heat half of the olive oil in a frying pan over medium-high heat and fry the bell pepper for 4 minutes. 
• Add the rest of the onion and fry for 2 more minutes, then add the honey and fry for another minute. Take the pan off the heat. 

Tip: if you don't like raw onion, fry it with the bell pepper instead.

• Stir in the za'atar and season to taste with salt and pepper. Cover with the lid and then set aside to keep warm.
• Transfer the pita bread to a parchment-lined baking sheet and bake in the oven for 6 - 8 minutes.
• Heat the rest of the olive oil in a frying pan over high heat and fry the falafel for 3 - 5 minutes until evenly browned.
