ya, i can't find any info on the pb handi snaxks either...i definitely ate them on several occasions. limited edition orange crackers!
only thing was this blurb on wiki:
Handi-Snacks were released by Nabisco in the mid 1980s and started with a cheese and cracker combination. These products were intended for consumption by grade-school students with their lunches. Nabisco tried peanut butter Handi-Snacks with crackers but later discontinued that product. With the acquisition of Nabisco by Philip Morris (now Altria Group), the products are now sold under the Kraft brand.
