Had the lamb last night. And I agree it is a tasty dish, and quite rich and filling, even without any potato. But the way the lamb fell apart, I did wonder if it was pressed together, rather than a proper cut piece of meat.
Overall, a good tray full - but we were benefiting from flying from MAD (to LHR).
And below, for comparison, is the post-breakfast offering on Iberia Express, which we got flying LPA to MAD. The pasta was very good, and both the starter salad and dessert were larger than their BA equivalents.
