Mixed salad. Generally speaking a mixed salad indicates that it is not a green salad. A mixed salad may have the same mixture of green leaves that populate a green salad, but might have a couple of tomatoes or some radishes, some red leaves or some peppers to jazz it up. Naturally, the quality of the mixed salad, and the green salad, will depend on where you are eating it. It only ever appears as a side dish.
Char(r) usually refers to the Arctic char, an uncommon freshwater fish of the same family as salmon, trout and related to grayling and the vendace or powan. It is found in rivers and lakes of northern Europe, north western United States and Canada and in the Great Lakes. They are migratory fish, like salmon and trout. They have a steely blue-grey back with salmon-pink speckles on the sides and a red underbelly. They have sweet firm flesh which varies from white to pink, dependent upon its own diet, and with good flavour, some say better than trout, being something like a cross between trout and salmon.
