If you're having a picnic then you should certainly consider some crackers as part of the wonderful mix of foods. There is nothing better than bread and cheese, but what about dipping a cracker into some hummus? You might want to consider your gluten free options as well and there are plenty of choices here. Crackers, cheese biscuits (or whatever you want to call them) come in a very wide variety from small to large to grissini to linque flat breads so you can choose yours' to fit the rest of the picnic foods.
