Cous Cous Salad

I cannot believe I have not posted this recipe. I should be taken out to the backyard and put out of my misery for not sharing this with you ladies. My sister, who helped me in my recovery from my back surgery loves this salad. She can never get enough and always makes me double if not triple the garlic. I have no idea where I got this one, but I think I got it the first time around as a vegetarian. But whatever the case, this is my most requested dish, and not just for the holidays.

1 cup cooked couscous
1/2 cucumber, peeled, seeded (an important step) and diced
1 medium tomato seeded (trust me you need to do this step) and chopped
1 bunch of green onions (I have tried substitutes...it doesn't work) chopped
1 cup chick peas

Dressing:
1/8 cup olive oil
1/2 cup lemon juice (start with 1/4 cup and add until it is right for you)
2-? cloves of garlic (I usually use about 4) crushed (or put through a garlic press)
1 t Dijon style mustard, coriander and salt
Some pepper to taste (go easy on this one. I LOVE pepper, but this is OK without it)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Mix first five ingredients. Then on the side in a small bowl, combine the dressing. I also tried adding the dressing right to the salad before mixing it separately...doesn't work. Mixing it on the side first is best. Add to salad, mix well and serve.
