A simple yet supple side dish for any day: Sauteed spinach with garlic, walnuts, and goat cheese that's ready in about 10 minutes. Always be sure to wash spinach well in a few changes of cold water, swishing the leaves around each time to loosen any dirt or grit, and then drying in a salad spinner or by spreading out on clean kitchen towels. Trim off the tough stems, too.
