Just cook it on medium high for about ten minutes with a little oil stirring constantly, you can add vinegar to help with the de-sliming process. If you have a pound of okra I'd say to add a couple of tablespoons of vinegar.
I use tomato to cut the slime and a little okra. sometimes I dice onion small and add sometimes I don't. season to taste and just cook it down slow until its as broken down as you want it. I let it cool then bad it into quart bags and freeze it.
