[quote JaneJeffer]@SheldonesqueIsUnwell I thought I had muddled my carbs and my mafs 
@NeverDropYourMoonCup that's not dinner, that's a side dish![/quote]
Not the amount I had, it wasn't. 
Tracked it afterwards. 86 calories for half a pound of cauli, 190 for the Béchamel, 238 for the cheese. Nowhere near my TDEE, but God, it tasted good and I wasn't hungry afterwards. Even if I'd had an entire cauliflower and a pint of sauce, I'd have still come in well under and had 'room' in the calculations for chips.
Mind you, I'd take boiled potatoes (preferably with chopped Dill), steamed veg and panfried Salmon over manky flaky/soggy/burned pastry any day, as well.
I think DP's going to the chipshop tonight. I'm debating about whether to have Spring Roll, chips and curry sauce or Prawn Balls, Salt and Pepper Squid and Green Lipped Mussels in Black Bean Sauce. Plus plain rice. Decisions, decisions...
(NB: I am really enjoying the OMAD thing - I think it shows, doesn't it?)
