What are the readily available snacks(in smaller quantities) which are healthy for pregnancy that I can keep in office to munch in between? I am in my second trimester. Please guide

Homemade foods are always good than packet foods.
Will suggest you to make some snacks at home and then keep it with you in office like roasted makhana, dryfruits ladoo, multigrain chivda, murmura, fruits, oats ladoo etc.
