2. Meanwhile, place grated potatoesin colander; squeeze out any liquid.Add potatoes to chorizo mixture, and cook 10 minutes, or until potatoes begin to brown, stirring often to scrape up brown bits.
3. Add liquid from diced tomatoes to pot, scraping up any bits from bottom. Stir in tomatoes, oregano, sugar, chipotle chile powder, ancho chile powder, and remaining 2 tsp. garlic. Season with salt and pepper, if desired. Cover, reduce heat to medium-low, and simmer 45 minutes, or until sauce is thick. Garnish with avocado and cheese, if using.
