Build your own items are always my favorite. Salads, bowls, whatever it may be. Chipotle, Qdoba, & Panera are all great catering options if you go that route. Let me pick my protein, veggies, etc. and let it all be fresh when I eat it! Soups are also great. Have coffee, water, soda, and some snack (granola bars, chips, goldfish, etc) type items available at all times! I also appreciate when meets provide a schedule of when food will be delivered. At the gyms I have coached at, we require coaches to be in awards with our athletes. Knowing when food will be delivered allows us to pop in and get our food hot and take it to awards if needed.
