Flounder is one of my kids favorite fish and this preparation is so simple. I dip the fillets in a lightly beaten egg, then dip it in panko breadcrumbs that I season with some salt. I use a mixture of butter and olive oil in the skillet - the butter adds a lot of flavor and the olive oil prevents it from getting too brown. It only takes a few minutes on each side so prepare the side dishes before starting the fish. Here I served it with a white bean salad and roasted asparagus.
