Tiziki!
I make it all of the time,
1 or 2 cucumbers peeled, deseeded and finely grated, leave in sieve and 1/2 teaspoon salt to drain a little
meanwhile crush garlic,
put cucumber into a bowl, mix in the garlic then add greek yogurt (I put in a big tub) and sometimes I add sour cream, but always add a few table spoons of olive oil then add lemon juice to taste. nom nom nom. serve with just about anything, can be used as side dish to meat, dip or salad dressing
