I am wondering if anyone can help me with something I am trying to find. I would like a recipe for lemon vinaigrette dressing for salads. When I was in the hospital in June with pneumonia they served it for the lettuce salads and I loved it. I was reminded about it again when I went for my heart cath and was in for the day while laying with the weight bag on the entry site. Also before they would let me go home I had to eat a meal or at least part of a meal. Again they had the lettuce salad with the lemon vinaigrette on the side. I really like it and they do not sell it in the stores. I checked every dressing there was at two major stores and no lemon. Raspberry and such, but not that one. Can anyone help me with how to make it? I would sure appreciate it.

Thanks,

Sue
