If you've been under the impression that moroccan stews must include meat or poultry, think again. A delicious vegetarian tagine with mixed vegetables can be prepared as your main dish. Vegetables cooked in traditional moroccan tagines have appetizing texture, color, and flavor. Cut the veggies into wedges or planks and arrange them in conical berber style, or simply slice and layer them. If cooking in a tagine, a diffuser is recommended for placing between the tagine and burner. If you don't own a tagine, a skillet may be used instead. Serve directly from the dish in which you cooked, using crusty bread such as moroccan semolina bread for scooping up the veggies and sauce. Avoid rushing the cooking; you'll want to allow one to two hours for the veggies to slow cook. If using argan oil instead of olive oil, extra care must be given to maintaining a low temperature so as not to ruin the delicate flavor of the oil.
