Seared Radicchio Mediterranean style. If you like radicchio, you will love this healthy and delicious recipe with complex flavours and textures. Simple and quick to make. It’s also known as Italian chicory and used in Italian cuisine. The bitter taste will mellow the more you cook it. I prefer somewhere in between so you still retain the crunchy texture. The radicchio is full of antioxidants, vitamins and plant phytonutrients making it a healthy choice.
