Sauté the onions and garlic in the same 5-Quart Cast Iron Dutch Oven (over medium to medium-high heat).
Toss in the bell peppers, celery, tomatoes, andouille sausage medallions and mix everything up.
Add the Roux to the pot of ingredients.
Add the beer and broth…one or the other or both.
Get the gumbo-in-the-making up to a nice simmering boil.
Add the filé and the thyme and stir in very well.
Check for Saltiness and add salt if needed.
If you added salt, let the pot simmer for another 5 minutes and check for saltiness again.
Cook until the vegetables are cooked to the consistency you like for them to cook to.
Serve into bowls and top with hot, cooked rice. Garnish with sliced Green Onions
Then, Bon appétit!
