I try to eat healthy when I travel, but it can be especially challenging when airport kiosks beckon with colorful candies and bags of chips. That's why I was so thrilled to discover Justin's Nut Butters - single-serving packets of nutty spreads that are small enough to pass the TSA's liquids/gels requirement when stowed in carry-on luggage. Just knead, tear, and squeeze delicious options like lightly-sweetened honey peanut butter, classic, salt-free almond butter, or the cocoa-rich chocolate hazelnut butter. A few of these guys, some trail mix, and a couple of pieces of fruit were enough to sustain me in good health through a recent 18-hour plane ride.
