I was brillant today.....I usually get pre washed salad or the organic salads in plastic container, but I still rinse and add whatever to it. Realizing I had leftover salad I put in large baggie so it is already 'pre-made' , does that make sense.
I found in the larger Dollar Trees w/refrig section real Feta cheese. Mix with nuts and Blueberry vingerette is wonderful.
Sometimes I'll add fruit, ie apples and oranges to the spring mix.
Another way from restaurant is to add (less than perfect lettuce), tomoato soup and taco seasoning.
If you have any leftover fresh string beans (which I saute lightly in skillet w/olive oil and add peanut sauce), refrig and then add to salad mix next day it is delish!
Blueberry vinegrette sounds wonderful. How do you make it?
