http://www.spanishdict.com/translate/legumbre (Legumbres is vegetables). I believe it is more common to speak of "Vegetable pastas" than it is to refer to "Legume Pasta", but that is my opinion, only! Nor would I personally use "conceived"
https://www.vocabulary.com/dictionary/conceive (personally, the first meaning of "to conceive" that comes to mind is "to impregnate/to become pregnant i.e. make babies, but of course, there is ""the idea is sometimes called "a seed" or "the seed of an idea," and conceive means to produce something from inside the mind."
