The airline clubs at the airport have been improving their food. In a pinch you could just eat off the buffet I found plain chicken available at 2 different airport clubs.
I wound up eating chicken I had in my bag but ate sone vegetables and cheese from the club. Then at my next stop I made another salad and added Epic bacon bits. There was olive oil on the salad bar so it was easy to get some good fat.
