Salad dressing served in restaurants are loaded with salt, fat and sugar, exactly what you don;t want to put on a healthy salad. I’ve advised in the past that you carry you own olive oil and vinegar to use when dining out. Small packets of each are available on Amazon, i buy them literally by the hundreds.

My resourceful daughter presented me with another option this Christmas when she gave me tiny dressing bottles from Crate & Barrel (full disclosure, she works for the company, so likely got these at a discount. You can get them on the store’s site for $4.95 each).
They’re a soft plastic and, as the instruction tag says, easy to fill with wide tops. They also can be washed in a dishwasher and go in a refrigerator. The tag also says they’re leak-proof.
I just got around to filling mine last week, so plan to test them out soon. I think I’ll carry them in a sealed lunch bag just in case, something I also do with my oil and vinegar packets which occasionally will burst open or leak.
Using these bottles will likely be cheaper in the long-run than buying packets because I can fill them from the large oil and vinegar bottles I get at Costco.
Thanks Daughter!
