MY grandma taught me to make it due or do with out. So, that's what I did. I didn't use Greek yogurt because I had some full fat French kwark to use up. And to be honest I didn't want it too sour so I skipped the sour cream and buttermilk. I did use a squeeze of garlic dressing and I didn't have Ranch mix but I tried to stay with the Mediterranean theme so I used some gyro mix - and then I didn't use chicken but a chicken like vegetarian substitute. <br/><br/>It was good and the surprising thing is my husband who doesn't normally like hummus and garlicky foods, he really liked it. But what I also did differently was used spinach tortilla's and a bit of fresh rucola and I ate mine cold at our picknick lunch, but I heated his warm in the oven - because he's one of those people who doesn't like cold food... he said it was great. I also made one for my friend that we met at the park for lunch - she really liked it too. <br/><br/>I left out the avocado and feta because my husband doesn't like it. I put it in for mine - it was good.
