Tips from the EatingWell Test Kitchen

These are the key tips we learned while developing and testing this recipe in our Test Kitchen to make sure it works, tastes great and is good for you too!

• You can toast the walnuts for more depth of flavor. Place chopped nuts in a small dry skillet and cook over medium-low heat. Stir constantly until the nuts are fragrant, 2 to 4 minutes.
• This sandwich calls for ciabatta rolls, but it would be just as good in a pita pocket or on whole-wheat sandwich bread.
• You can make the spread in advance; it will be good in the fridge, stored in a covered container, for up to one week. Save time by slicing the mozzarella and tomatoes ahead of time and storing them in separate airtight containers in the refrigerator.
