what do YOU serve for dinner with beef/calve's liver (and onions)?

My family surprised me by enjoying liver and onions, and since it's healthy and cheap, I'd like to make it once in a while. But while we like it, we don't really stuff ourselves on it, so we need a some great somewhat filling side dishes to go along with it. Last time I did an Italian recipe with a huge composed cooked vegetable salad. This time I wanted to do a southern style meal with biscuits. But what else? What do you serve with it (southern or not)? Or how do you serve it?
