In the tajine, add oil, chopped onion, and green bell pepper. Form small balls with the ground beef and place them on top of the onion and green bell pepper. Then add sliced tomatoes, and finally, sliced red bell pepper.

Sprinkle the spices over everything, or mix them with a little water and pour over the top. Garnish with olives, and cook on very low heat. It needs to cook slowly because it doesn't contain water, and it turns out delicious.
