get some wraps and make yourself lunch with grilled chicken and veggies or steak and veggies or anything you have leftover
try cooking enough at dinner that you have fixings for lunch a few days...it really does help
Also the tangy black bean soup was a lifesaver for me....made the whole recipe, divided into 8 freezer containers......made a salad and grabbed a container of soup..easy
Good luck you will find what works if you keep at it
