Just picked up a couple of jars of Slawsa while doing some Roadhouse Bar-B-Que Sauce promotional work at the Heinen's chain in Cleveland. It is in fact very similar to a chow-chow both in flavor and appearance. Anyone expecting any level of genuine heat from the Spicy version will be disappointed, but the flavor is pretty darned good. I've been using it on Brats and Polish for the last week with great success.
Heinen's had Slawsa on sale for about $3.69 when I bought it; regular price over four bucks.
I'll bet they've got it at their new Chicago stores too, so I won't have to travel as far to get more.
