Hungryroot (weekly deliveries start at $59) is a supercustomizable grocery delivery service that has made lunch (and dinner time) so easy when I have no time to meal plan and prep.
The grocery plans come along with corresponding 10-minute recipes, which isn't too intimidating to tackle on my lunch break. You can also indicate your dietary preferences when you order — for example, I'd note that I only want vegan and peanut-free options.
