I just made a sweet potato salad that I serve at room temperature. The recipe says serve "warm or room temperature" and it got me thinking- what defines a salad as a salad? Pasta served warm is a pasta dish. Served room temperature or cold it is pasta salad. Potato salad is potato salad warm or cold. So, it's not the temperature. Slaws are salads. Salads can be made with vinegar of without. Mayo, no mayo, oil, no oil.
