I have been catching a lot of these guys lately as bycatch while targeting flatties and releasing them all not realizing that they are regarded as good eating

. That leads to several questions. How good are they really? What parts do you eat? Best ways to prepare? I fish once or twice a week and throw back way more than I keep. Love variety and extremely fresh fish so I want to learn about this fish as a possible addition to the occational keeper list. Thanks in advance for the eduacation.
