In a large saucepan heat the olive oil over medium heat and saute the onion and garlic until soft but not brown, about 3 minutes. Add the lemon zest and olives and cook for 1 more minute. Add the white wine, deglaze the pan, and let it reduce for a 1 to 2 minutes. Stir in the stock, canned tomatoes, sugar, red pepper flakes, and cinnamon, and simmer to blend flavors, about 7 minutes. Season with salt and pepper, to taste.
