In a large non-skillet saucepan over medium heat, sauté the onions for 5 minutes or until golden brown. Using a slotted spoon, remove the onions to a bowl. Add the meatless tips to the saucepan and sauté for 5 minutes or until browned. Add the garlic, wine, salt, cinnamon stick, cayenne pepper, black pepper, Bay leaves, granulated sugar, tomato paste, and 1 and ½ cup of boiling water, and stir to combine. Add the potatoes, and onions, bring to a boil, reduce to low heat, cover the saucepan with the lid and let it simmer for 18 minutes or until the potatoes are fork-tender. Taste and add salt, and black pepper if needed. In a small bowl, make a slurry: whisk the cornstarch with 3 tablespoons of water until smooth. Add the slurry to the stew, constantly stirring until it thickens, about 30 seconds. Remove from stove. Remove and discard Bay leaves and cinnamon stick before serving.
