I agree, most low carb eating seems to require cooking and I can't be cooking even something as simple as bacon and eggs at breakfast time. Oh for the days when preparing breakfast was just a matter of tipping muesli into a bowl and adding fruit and milk! My solution is to buy packs of free range chicken legs (Morrisons) and cook some the night before. At first the idea of chicken for breakfast did seem a bit odd, but I quickly got used to it. This does mean that every night I have to find time for some (pretty simple) cookery. If I am going to be out for lunch, my standby is low carb cheese and nuts. Full fat Greek yoghurt is portable and low in carbs too.
