Reading all the replies has made me realise we have an awful habit.
We've had 2 this week already, its only Thursday. We will more than likely have one on Friday night and then probably Saturday too because it will be too late to defrost any meat by the time one of us thinks about it.
And if you count lunches as takeaways, then it's every day! I have maccies brekko at least once a week and get my lunch from either Greggs or Tesco every day.
We often discuss how much money we waste on food, but neither of us have the inclination to cook after a busy day at work.
