Hamburger (veg or not) with radicchio and… yogurt souce

There’s no need to explain how to make a sandwich, on the other hand the yogurt sauce is very innovative, compared to that rubbish they give you around! Simply put 1-2 tablespoons of yogurt in a glass and add tomato puree, paprika, curry, turmeric, garlic, oil and you have a healthy and tasty sauce! The radicchio is simply cut and sautéed in the pan.
