Meal Prep Suggestions

I'd like to get started with meal prepping once or twice a week for 2 people. What are your favorite recipes or websites for meal prepping? Thanks in advance!

As an additional note, my fiance is a Type I diabetic, so lower carb meals are preferred. A side of rice or pasta is okay, but the whole meal shouldn't consist of it. He tries to keep meals under 40g carbs. We both have access to a microwave at work.
