1. Select Saute on your pressure cooker and set to 10minutes. Then when hot spray the pot with some nonstick spray then add onion and saute until softened, this should take about 5 minutes.
2. Next add the cauliflower, potato, celery, thyme and the salt and black pepper. Mix until well combined and cook the vegetables stirring now and then.
3. While you wait for the veggies to soften a bit, whisk the flour with ½ cup of the chicken brown until it’s lump free and well combined. Carefully pour over the vegetables.
