Here’s an interesting summer snack that requires no refrigeration: the new Gaea Olive Snack Packs. They’re individual portions of pitted olives that you can carry around in your purse or beach bag. They come in three varieties: kalamata olives, or green olives marinated either in chili and black pepper, or lemon and oregano. The kalamatas are 150 calories per pack; the green olives are just 67 calories. They’re $2.49 and available at stores such as Kings Food Markets, Whole Foods, Total Wine and Acme.
