Yes! I would start with a yeast-based savory dough or perhaps store-bought puff pastry or pie dough. I first tasted savory pizza hamantaschen at Breads Bakery in New York City. Be sure to check out my friend and cookbook author Emily Paster's savory hamantaschen recipes. Emily has a vegetarian filling, lamb filling and beef filling. I bet za’atar, tomato and feta would be a good combination too!
