The main reasons I've seen from vegans for not eating meat seem to be all about the morality of eating a sentient animal, the practices of the modern meat industry, and the environmental impact of it. And don't have anything to do with the taste of meat.
Since lab-grown meat doesn't cause animal suffering, and assuming mass production is environmentally friendly, would you consider going back to eating meat if it were the lab-grown kind?
I would eat it, but I would do so on rare occasions in the same way I might have a drink with friends once a month.
I became vegetarian for health reasons in addition to the reasons listed by OP and I have grown to really enjoy meat-free eating, so I don't really miss it but would view it as a treat best enjoyed sparingly.
