How to get started?

My boyfriend and I have taken on a low carb diet. I really want to get into meal prepping to make my life easier. I only want to do this for lunch as I love to cook and have a arsenal of low carb dinner recipes I'm dying to try. I was wondering if anyone has tips on how to get us started! He works on the road so heating things up cannot happen for him. I work in a Med office and have a microwave handy. What would be my best options here? Thanks in advance! Also, sorry for formatting in on mobile!
