suggestions

I need a few suggestions when it comes to Mid morning meals and mid afternoon meals. I work in an FDA regulated environment so I have to bring my food into the plant in the morning and cannot bring anything into the plant after i leave for lunch. Could someone make a few suggestions about these meals please. I don't want anything too fatty because I am still trying to keep a clean diet and minimize the fat around the GUT area.

I know things such as tuna, fluit, cottage cheese...... I have a lottle cooler with some of those blue ice blocks that stay cold all day.

Thanks
