Unless you are looking for a particular flavor, what about making your own? Very simple - oil of your choice, good quality vinegar of your choice plus seasonings of your choice, shake and refrigerate. Or even simpler, a small drizzle of oil on your salad, followed by a shake of seasonings and vinegar to taste. Here is just one example, but you can find thousands on line
Peeled garlic clove in a bottle, add 1/4 cup high quality oil, a grind of fresh pepper, a grind of sea salt, 1/4 - 1/2 teaspoon of dried herbs (I like rosemary, basil & oregano) and about 1/2 cup of good balsamic vinegar or red wine vinegar. Shake vigorously now, refrigerate, an shake vigorously before using.
Have you though about making your own dressings?
