If your dressing is made from ingredients that do not need to be refrigerated (such as dried herbs instead of fresh), then you can leave the dressing at room temperature for a few weeks. If refrigerating, sometimes the olive oil in the bottle turns a little solid, so let it sit out on the counter for about 10 minutes before using.

Try pureeing a few fresh strawberries or raspberries, and throw them into the mix for a yummy spring salad.
