I made this today and was very impressed with its flavor!
For the dressing.....1 tbsp of Vegan Mayo, Dijon mustard, lemon juice and Chia seeds! VERY GOOD!!
Note : For the Vegan Mayo. I get mine from Whole foods. The Brand is Follow Your Heart and I get the Light version. 1 tbsp 45 calories and all clean ingredients, for a sweetener, agave nectar is used. All you need is 1 tbsp and this will yield several servings.
