Combine the ground chicken, cilantro, Dijon, Ras el hanout, saffron, dried onion, and garlic powder in a large bowl and mix it all together thoroughly with clean hands. Press it into a single, even layer, then score it in half both vertically and horizontally to make four equal quarter pound portions. Heat an electric griddle to 400 or a griddle pan over medium high heat. Form the four equal portions into patties and sear them for 5-6 minutes on each side to cook them completely.

While they cook, toast the hamburger buns. Butter them once they're done and place a cooked chicken burger on each bottom. Top the patties with a heaping spoonful of the hummus and a small handful of baby spinach. Serve them immediately with your favorite side!
