I'm starting a thread for recommending particular meals on CE to each other as some of us probably have an opportunity or two to wonder which one to have. Maybe we can help each other to find a good meal.
Overall I find CE meals to have improved recently, but there are some really nice ones around.
Of course how it comes out would depend on how it's been heated, but out of the recent selections I have found the following to be rather good (not that others have been bad, but I liked the following more than others):
Hot Smoked Salmon with Vegetables (LHR Band 3 lunch time)

LHR CE Band 3 Hot Smoked Salmon
I had this today and it was surprisingly good. The salmon was cooked nicely, and the sauce was light but with lovely flavour to it. Vegetables were a bit "boiled" but not mushy.
King Prawn Linguine (LHR Band 3, either lunch time or dinner time, not sure)

LHR CE Band 3 Prawn Linguine
As the name suggests, it has king prawns on linguine. It's not completely overwhelmed by the prawns but there are enough of them, and the linguine has some green leaves (not sure what? spinach?) in it too. Sauce is creamy but not too heavy.
What are your recommendations?
