Croquettes are not “something veggie”. You can make them as breaded bechamel, but often they’re filled with pork ham or chicken bits. You may find more fancy varieties with seafood or mushrooms, but overall I wouldn’t consider them “something veggie”.
Is Spain primarily meat-eating? Yes. If that’s your concern, be upfront about it but don’t generalise saying that Spain cuisine sucks.
Nothing against primarily-vegetarian or vegan cuisines. I’m only against saying “this cuisine suck” when you really mean “I don’t like it”.
