What would be good side dishes for this?

I will be making roasted potatoes and sausage for dinner. I just cut potatoes and smoked sausage into bite side pieces, season the absolute shit out of them, and then bake them.

I usually make corn casserole with it, but we want something else with it tonight as well. My husband is an extremely picky eater, so any other veggies are out, along with salad. I was thinking maybe mac and cheese if I can't come up with anything else.
