This salad is best the same day. Quinoa is a cereal sold mostly in health food stores. Ask for it at your supermarket.
Whether to bring them to a picnic, to eat outside, or to serve on a buffet, dishes containing cream or other dairy products, eggs, mayonnaise, meat, fish, or poultry must be kept no longer than 2 hours at room temperature. This standing time is even shorter when the food is exposed the hot summer days. Do not forget to place an ice pack in your picnic basket.
