In Spain, a green salad is almost always on the table at mealtime. "Ensalada mixta" or a colorful, mixed green salad is served on a large platter. It usually includes a mix of ingredients that Americans may find surprising, such as olives, tuna and white asparagus, as well as tomatoes and onions. Easy to prepare, it is as tasty as it is attractive. Perfect for dining on the patio or terrace this summer.
