6 lg. white or yellow onions, chopped
Too much IMO. And chop this fine.
1 sm. bell pepper, chopped
I'd go with 1 large bell pepper.
1 tbsp. chopped celery
Need a good bit more than that.I use 2 or 3 stalks, and again chop pretty fine.
3/4 cup all-purpose flour (for roux)
1 cup cooking oil
I never measure, but I would use more flour than oil.
6 cup hot water
Switch to chicken stock. Makes a big difference.
I do about the same procedure, except I put the garlic in right before the chicken and sausage. And sometimes when I'm feeling lazy, I use a rotisserie chicken.
