italian chicken sausage?!
Italian sausage can be labeled as regular or spicy, but isn't always. If you are buying it from a butcher shop, ask them. If you are buying a packaged brand hopefully they will have two kinds. If there is only one kind, check the ingredients for pepper or some sort. Otherwise, you just have to take your chances.
I've tried the Jenny-o Turkey Italian sausage and it's not too spicy. Maybe try that.
