I try to keep a stash of single serve hummus and guacamole in the freezer for emergencies. Sometimes I make it, other times I buy it.
chia pudding (3T chia seeds to 1 can of coconut milk, maybe a little sweetener or flavor extract, maybe not. Shake in a mason jar and refrigerate overnight)
homemade lara bars - if I roll them in unsweetened cocoa my kids won't touch them
coconut chips (Trader joe's has good ones)
