Merguez Seasoned Kefta Kebab Sandwich

This is a sandwich I made for a middle eastern kebab sandwich. But we make the same in Algeria. It's ground beef seasoned with merguez spices and shaped onto a steel kebab skewer and grilled. The garnishes are very simple, just sliced tomatoes, sweet onion and greens. A good lashing of harissa mayonnaise is optional.

This is my merguez spice blend. I add over a dozen spices to it. You can see how red it is, the characteristic color for merguez.
