B: left over DietDoc frittata - delicious, but I took 
@Chook 's advice and cut the butter and mayo right down.  worked out about right, I think.  That is the last DD food until Friday night.
Late L: 2 tacos with guacamole, cheese, sour cream and a little pulled pork in too sweet a sauce.  Very nice, but the tacos gave me the highest reading I have had for 3 weeks.  Lesson learned.  Followed by 8oz steak, mushroom, peppers, grilled tomato.  Gave the onion rings to Mr B and left the chips.
D: definitely not needed!
Off to stay with relatives tomorrow, where I have no control over the kitchen.  Should be interesting.
I have nuts, dark choc and chia bars in my bag, and have put in a polite request for cheese and ham in the fridge.
Am also taking some local butcher's fab gluten free sausages - they are delicious.
And a low carb apple crumble cake
and a small lake of double cream
Here is the cake recipe.  very easy, and very good.
