This recipe is very tasty and different from the usual cucumber and onion salad. It is richer in flavor, because I use (VEGENAISE - ORIGINAL) instead of mayonaise. Use the "Original" not the grapeseed vegenaise. Vegenaise is FREE of dairy, eggs and glutens. You can buy Vegenaise at Sprouts or Vitamin Cottage. The red kidney beans and mushrooms also make it different from the usual cucumber salad, but very delicious. Everytime I make this salad, my husband comes back for seconds and thirds. I always double the recipe. It makes a wonderful side dish to any meal. NOTE: You may want to soak the cucumbers in salted water first then drain & blot dry with a paper towel before adding to ingredients, this keeps your cucumbers from making the vegenaise watery.
