First of all, unless you know what you're doing, don't use any courts apart from just courts, as most regions only need just courts.
Second of all, sell your food according to your banker/duke/whoever organizes such in your realm, for it benefits you and your knights.
Third of all, tax your region appropriately, I shall elaborate on this later. Most regions should have "some people are complaining about taxes" and no more, no less.
