Needing low-carb meal ideas

Jon is diabetic. He hasn’t been taking care of himself for awhile now and the doctor’s office got on him about it recently, which is good because if they weren’t I was about due to start. They sent him home with some insulin pens to get started back. The problem is that he has not started back because we’ve been pretty carbed-out at supper time for awhile now. I guess insulin and carbs do not play well together.

Any suggestions of good low (or no) carb meals that we could make?
