This was inspired by the artichoke dip at Freeman's, which is reportedly made with a base of mayo and parmesan. Though that dip is really amazing, I think it's probably uncessarily heavy for tonight.
So I caramelized some onions, adding a different sort of sultry richness, and rough chopped them with artichoke hearts. Mixed them both with Greek yogurt. I wanted to add some herbs or something, since the whites and browns of onion, artichoke and yogurt don't especially pop on camera.
But the dip is so good on its own, I resisted.
