Is hummus fit for a king?
For purposes of bishul akum, a spread, even if generally served at important meals, is not considered an “important food” that will fall under the prohibition.
See Teshuvos Ve-Hanhagos Vol. 5, Yoreh De’ah 249, sec. 6, who notes this principle.
Concerning humus beans, there is a broad dispute among authorities concerning whether this is “fit for a king,” and although the custom was to be lenient some authorities rule stringently (see Bein Yisrael la-Nochrim 11:1).
