Why don't you share some meat with him? Who told you that Muslims can't share the meat of sacrifice to their non-Muslim friends? I have never heard of such ruling. The meat that is given to the poor (1/3) must be given to Muslims who are poor but you can share the meat which is part of your share (2/3) with your friend and other non-Muslims.

Sahih Al-Bukhari Hadith 7.476: Narrated by Salama bin Al Aqua The
Prophet (saws) said: (Of the Sacrifice) eat of it, and feed of it to
others, and store of it.
Fiqh-us-Sunnah Fiqh 5.115: A person offering
a sacrifice may consume, without any restrictions, any amount of meat
he may desire. He may likewise give away, or offer in charity any
amount he may wish. Some scholars say that one may eat half, and give
away the other half in charity, while others say that the meat be
divided into three parts. Of these one may keep a part, distribute a
part, and give in charity the third part.
