Great veggies gumbo! I tend to find with all gumbo that I have to season it up at the end (way better to be safe then being over seasoned) so I did end up doubling the red wine vinegar, hot sauce, adding cayenne and more sat/ pepper. I also added a green bell pepper along with the poblano. My spouse and I really enjoyed it and will enjoy the leftovers. * To make this gf I subed cornstarch for flour and also coconut oil for whatever oil was recommended. I have done this everytime I make a roux and have never had a problem.
This isn't the gumbo I grew up eating in Louisiana but it's delicious!
