So usually if I am gonna take a lunch it derives from the dinner i had the night before. So one i really love is pork chops, broccoli and rice. Putting them in containers to travel with sufficiently. But even if you work from home you can still pack the lunch for that designated time. In your lunch you should include a vegetable, protein( meat- the size of your palm, and a starch/ carbohydrates, like rice or potatoes( macaroni and cheese). I hope this helps. Be kind to yourself if this is new for you( even if you are a vet and have been doing this for a while)!
