I found these prepackaged meals called GoPicnic - I got a Groupon but I believe they have them at target. It is pre portioned and does not have to be refrigerated. The only one I have tried is the hummus and crackers but it is perfect bandster size (for me) and it has 19g of protein. It works for me when I don't have time to meal prep.
They have a huge variety and are worth it!!!
