Re:Side Dishes on a Cart.
Not much hassle or time....
Two ways to do it.
One, make a big batch from scratch and freeze it in one qt. bags.Throw everything together and it cooks itself. If it doesn't sell I've got beans to last the winter.
Two, use canned beans and kick them up a notch with pre-cooked rib meat or pulled pork. Can be done right on the cart.
Can offer to cut up a weenie into it or use it as a topping instead of chili.
Biggest hassle would be finding the best container to serve in.
