Curious to hear what others send/take to the office. Or serve for lunch/have available in the afternoon, because, you know, when they arrive after long flights, drives, bus rides, they are hungry.
One answer is to serve some kind of potatoes, either potato kugel or potato salad with tuna, chicken, or egg salad solution.
Cheese with fresh fruits and veggies. There are some fabulous bries and camenberts for Pesach.
If there is time to make quinoa into flour in the blender/food processor, you can use it to make delicious banana bread. I do them as muffins, very popular.
This year, I am thinking of making a sort of loaf/quiche/kugel using cooked quinoa baked with cottage cheese, crushed pineapple and eggs.
