I don't bother to make an actual vinaigrette here. Just toss all ingredients together in a bowl. Adjust seasoning. Enjoy!
Notes
This "recipe" is easily adapted to your tastes. Use your favorite lettuces, veggies & sardines. I use Wild Planet exclusively as I think they are the best. For this recipe I used boneless packed in water to let the Persian Olive Oil shine, but I often make the salad with the whole sardines packed in lemon & olive oil. If you use them just omit the olive oil and use a bit of the oil in the can, and swap your lime juice for fresh lemon juice.
