> commercial salad dressing almost always has sugar in it. Look at the nutritional facts label next time you're shopping for it. There's a few brands that offer "simple vinegar and oil" style dressings that don't have any sugar in them, but MOST salad dressings Americans come in contact with are full of sugar.
Making salad dressing is really easy btw in case anyone wants to try. Often all you need is olive oil, vinegar, salt and pepper and you're set for most salads. Even a restaurant should be able to whip that up.

Why do you need a "dressing"? In my corner of Europe they put the above by default on every restaurant table and the salad has nothing in it (or maybe a tiny bit of oil and vinegar), you adjust it to taste.
The only places that offer salad "dressings" are american inspired and even those mostly serve it separately so you can ignore it.
If you have an immersion blender, making mayonnaise without sugar in it is very easy:

I love this author's recipes; it's the opposite of the normal recipe-preamble-slop. All of the stuff before the actual recipe is relevant information. In more complex recipes, he goes over the testing and process that led to the finished recipe. It's a wonderful view into the world of recipe creation.
