My wife and daughter are practicing vegetarians. My wife also wants to eat low carb, but it's difficult to find things for her. Her first rule is "no meat" so grocery shopping is an adventure.

But during the week, I have changed things so she only prepares me fish. However, I eat meat and chicken for lunch (away from the house). It's a compromise.

Good luck in your efforts to find low carb veggie stuff. It can be done (she does it) but things like pasta, bread, those are a no-no to me but for her....
