For salad dressings, look for the old fashioned "bad" dressings! LOL High fat, low carb.

I use several: Kroger Pepper Parmesan (2g carbs), Ken's Greek (1g carb), anf Kraft Classic Caesar (<1g carb). (These counts are for 2T serving)

Read the labels. There are a lot of good dressings out there. And just for fun, check the carb counts of some of the "healthy" light dressings!
