Nuts, fruit, string cheese, and crackers that do not melt or crush before 3 p.m.
Wash grapes and berries once, then portion into containers so the fridge door is ready. String cheese needs an ice pack if it rides in a backpack.
Almonds and pretzels handle heat better than chocolate in Mississippi summers. Keep trail mix for cooler months.
Crackers with peanut butter beat chips when you need something that lasts past the afternoon meeting.
