Preheat a heavy 4-quart pot over high heat until very hot, about 3 to 4 minutes. Add 2 cups of the onions, 2 cups of the bell peppers, andouille sausage, and 2 tablespoons of the seasoning mix. Cook, stirring and scraping the bottom of the pot every 3 to 4 minutes, for 20 minutes. If necessary to prevent burning, add a little of the chicken stock, stir well and scrape the pot bottom and continue cooking. Reduce the heat to low and add corn, tomatoes, flour, garlic, the remaining onions and bell peppers, 4 cups stock, and the remaining seasoning mix. Cook, stirring and scraping the pot every 8 to 10 minutes, for 40 minutes. Stir in the remaining stock, return the heat to high and bring the soup just to a boil. Reduce the heat to low and simmer for 15 minutes. Remove from the heat and serve immediately.
Combine the seasoning mix ingredients in a small bowl.
