I love the spinach and kale bites in the frozen appetizers section. I'm at regular diet phase and I often 1/2 lean ground beef patty and 2 spinach bites (sometimes only 1 & 1/2) for lunch. They are extremely portable, as I take them out frozen, put them in the container with the frozen half patty and then microwave at work.
Also fantastic for portability to work are the turkey meatballs. I eat two meatballs and two spinach bites for lunch.
