Grain: In a pot with a tight-fitting lid, gently warm olive oil. Sauté carrot and onion together with salt and turmeric (onion will soften and become translucent). Add water and grain. Bring to a boil, turn flame to lowest, cover pot and simmer until grain has absorbed all the liquid, about 45 minutes.
Stew: While the grain is cooking, in a large saucepan, gently warm olive oil and sauté onion until soft, about five minutes. Add garlic, and stir another minute. Mix in spices, diced tomatoes, carrots and zucchini. Bring to a boil. Turn flame to lowest, cover pot and simmer 20 minutes. Add lemon. Season to taste with salt and pepper.
Spoon grain onto serving platter, or onto individual plates. Form well in center of grain. Spoon stew into well. Sprinkle with cilantro. Garnish each plate with a lemon wedge. Voila!
