2.288

若欲食者且待須臾。當令汝得未曾有食　三許也。小乘以禪悅法喜為法食。以五欲段食為毒食。今香積之飡食了得道。為未曾有。

“If you wish to eat, wait just a moment. I shall cause you to obtain food such as you have never had before.”
[Part] three: the permission. The Hīnayāna takes the joy of dhyāna and the bliss of Dharma as dharma food, and takes the morsel food of the five desires as poisonous food. Now, after eating Gandhahastin’s meal, one attains the Way; hence it is ‘never had before.’
