Kids are drawn to individual-sized snacks, colorful wrappers, and a whole host of other marketing tactics for packaging and kid's food. Make new, unfamiliar foods more easily identifiable by offering in their original packaging.

Packaging and Kid's Food
My two year old always wants to reach in the bag, have a small ziplock, open the wrapper, get individual-sized snack foods, or pick a new food all because of its outer appearance. There is an element of both intrigue, independence, and association with packaging and kid's food. Even when they can't necessarily see what is inside, a mental note is made and later they have an association established about what it is inside the package based on what they see on the outside.
Run with this and use it to your advantage, especially when offering a new "learning it" food. When packing such items in lunchboxes, consider including the wrappers (when age-appropriate to open it). You don't need to buy all individual-sized foods, especially given the healthfulness is often compromised and at a higher cost for such kid's foods. Instead, consider which foods you may be able to keep in at least some of the original packaging, even if using a bento box as we do.
This eliminates some of the unknown for unfamiliar foods, but also helps them to visualize what the packaging looks like to aid in the repeated nature of future food exposures. I have no doubt that if I included a LARABAR in my daughter's lunchbox without a wrapper, she would not have touched it. It is too unidentifiable. But having seen me eat them several times, she knows that the wrapper signifies another food exposure rather than something totally foreign and unfamiliar.
