Those are perfect looking slices of pork loin! Nice and juicy. Now I'm hungry.
We do not see chicoree ( english spelling: chickory ) used much over here in North America....Sometimes - in a very nice restaurant it will be included as an ingredient in a salad. But it is a nice addition to your plate!
You are right, I only see chicory occasionally in the produce section of nicer, up-scale grocery stores. It's sometimes called Witloof Chicory or Belgian Endive. I've not had it in a long time. I'm going to have to look for some now and try it sliced in half on the grill.
You see chicory growing wild here in the U.S. along highways and has bright blue flowers.
