Avocado tzatziki

Tzatziki has always been a constant in my world. Sometimes I throw one together to go with a quick weeknight meal. Other times, I take my time to strain the yoghurt for a richer, creamier version of this beloved Greek dip. And other times, I like to change things around, like I have today. Tzatziki is wonderful on its own, but with the addition of avocado it really goes up a notch. Cooling. Creamy. Sensual. This would work well with some pita bread and pork souvlaki.
