A lot of the cost per calorie is in preparation; if you can cook your own meals, you can reduce your cost per calorie signficantly. The problem is a lot of people don't have the time (or maybe will-power) to cook every meal; a few of my previous jobs made it very difficult to cook my own meals, so I ate fast-food alot, and gained a lot of weight.
When your boss starts pushing Return To Office, ask if the company has a worthwhile kitchen in the office; at least a burner and plenty of room in the refrigerator for ingredients; it should be feasible to cook breakfast and lunch, but also dinner, in case you need to work late.
