Tell me about everything. That looks delicious! (except the olives 🤮)

I’ve never made gumbo before but reading the recipie, don’t you brown the veg? Wouldn’t it also make more sense to make the roux after browning the sausage (and vag) and using the same pan so the roux dissolves the oil and crust from the browned veg&sausage? That recipe feels like it’s throwing a lot of flavour away if you follow it as written.
