Sprinkle the meat with a spice blend of the cumin, coriander, chili, cinnamon, salt and pepper, and then dredge in flour. Heat the EVOO in a Dutch oven over medium-high heat. When the oil smokes, add the meat and brown all over. Remove to a plate, reduce the heat a bit and add more EVOO, the chiles, onions and bay leaves. Cook to soften, 6 to7 minutes. Stir in the tomato paste, stock, zest and juice. Once the liquid comes to boil, add the meat back in and reduce the heat to thicken it a little. Serve with flat bread or couscous.
