Why not Holy Eucharist if you are thankful?
You may call it whatever you choose. It was Christ who said “remembrance”, the prayer of thanks and blessing (eucharist) came to be applied to whole later.
And Paul added that so long as the meal took place the death of Christ was proclaimed. (1 Cor. 11:26)
So call it what you wish but what is more descriptive and reflective of Christ’s command.
