Brown turkey and the onions together over medium heat in a large stock pot. When onions are soft add the peppers and garlic. Continue to cook 4-5 minutes until turkey is browned. Deglaze with the wine and add the rest of the ingredients except the hominy. Bring to a simmer and cover. Stir occasionally and cook 20-30 minutes. Uncover and add hominy. Cook for an additional 10-15 minutes, stirring occasionally.
