Ok, this is tongue in cheek, but we know Esau getting this Vegan meal was the first of his troubles with Jacob.
Esau Sells His Birthright
Gen 25:29 And Jacob sod pottage: and Esau came from the field, and he was faint:
Gen 25:30 And Esau said to Jacob, Feed me, I pray thee, with that same red pottage; for I am faint: therefore was his name called Edom.
Gen 25:31 And Jacob said, Sell me this day thy birthright.
Gen 25:32 And Esau said, Behold, I am at the point to die: and what profit shall this birthright do to me?
Gen 25:33 And Jacob said, Swear to me this day; and he sware unto him: and he sold his birthright unto Jacob.
Gen 25:34 Then Jacob gave Esau bread and pottage of lentiles; and he did eat and drink, and rose up, and went his way: thus Esau despised his birthright.
Btw, Esau was a hunter and I doubt he was strictly Vegan. Maybe Daniel was…but I don’t think this was done for Vegan reasons.
Gen 25:27 And the boys grew: and Esau was a cunning hunter, a man of the field; and Jacob was a plain man, dwelling in tents.
Gen 25:28 And Isaac loved Esau, because he did eat of his venison: but Rebekah loved Jacob.
Dan 1:8 But Daniel purposed in his heart that he would not defile himself with the portion of the king’s meat, nor with the wine which he drank: therefore he requested of the prince of the eunuchs that he might not defile himself.
Dan 1:9 Now God had brought Daniel into favour and tender love with the prince of the eunuchs.
Dan 1:10 And the prince of the eunuchs said unto Daniel, I fear my lord the king, who hath appointed your meat and your drink: for why should he see your faces worse liking than the children which are of your sort? then shall ye make me endanger my head to the king.
Dan 1:11 Then said Daniel to Melzar, whom the prince of the eunuchs had set over Daniel, Hananiah, Mishael, and Azariah,
Dan 1:12 Prove thy servants, I beseech thee, ten days; and let them give us pulse to eat, and water to drink.
and let them give us pulse to eat, and water to drink; instead of the king’s meat, pulse, beans, pease, vetches, lentiles, rice, millet, and the like. The word (d) used signifies anything sown, all kinds of roots, herbs, and fruits; and, instead of wine, water; meat and drink, it may be thought, that persons of such birth and education had not been used to; and yet they preferred these to the king’s dainties, by eating and drinking of which their consciences would be in danger of being defiled.
Dan 1:13 Then let our countenances be looked upon before thee, and the countenance of the children that eat of the portion of the king’s meat: and as thou seest, deal with thy servants.
Dan 1:14 So he consented to them in this matter, and proved them ten days.
Dan 1:15 And at the end of ten days their countenances appeared fairer and fatter in flesh than all the children which did eat the portion of the king’s meat.
Dan 1:16 Thus Melzar took away the portion of their meat, and the wine that they should drink; and gave them pulse.
