Serves 6 to 8 Re tzatziki: Use these measurements as a guide. I like my tzatziki garlicky, but others do not. Also, I have received comments on other posts that tzatziki isn't tzatziki if it doesn't have cucumber, but that's really not true. If you like adding cucumber, by all means add it, but it is not necessary. For the salad: Use these measurements as a guide. The dressing for the salad is simple: equal parts olive oil and white balsamic vinegar.
