really depends whether you accept that the uruk hai are the result of cross breeding between humans and orcs. there are suggestions throughout the lore that this may be the case, but in the FF, gandalf states that they are the result of crossbreeding between orcs and goblin men. in any case, let’s assume for a moment that theory one is correct and that the Uruks of Isengard and possibly Mordor are human-orc hybrids. It stands to reason that these Uruks would have retained traits from both species - ordering food from a menu, for example. Furthermore, one of the Uruks is heard to complain about ‘maggoty bread’, suggesting a considerably sophisticated pallet.
The theory is somewhat clouded by dialogue in the same scene between the Uruk captain and two of the orcs, one of whom asks for a slice of meat off the ‘flank’ of the hobbits whilst the other is seen licking his lips at the prospect of consuming one of the most tender cuts of meat - the leg. You could infer from this that the traditional orc or goblin possesses the capacity for a la carte dining too. Furthermore, the logistics involved in moving an army the size of the attack force at Minas Tirith would have probably necessitated the mobilisation of an orc catering corps or equivalent - the idea that such a force could have lived off the barren wastes between Mordor and Gondor is, in my mind, unacceptable. If the orcs were capable of organising such a corps, it stands to reason that a range of food would have been available at the orc mess, or equivalent, much like a menu.
I mean, I could go on.
