Im a vegetarian but understand completely what you're saying &, I think, feeling. I have no argument with my hunting friends who respect the animals they hunt & kill & eat. I can't kill animals (have tried) & so chose to become a vegetarian.

The manner of death & the executor's relation to it & to the sacrifice is key, which is I think your point. I'm sorry your husband doesn't get it. You are wise to seek some compromise that doesn't demand understanding.

The grill seems workable, since the heat would be sufficient, but the animal would still need to be killed first. Perhaps electrocution would be the most simple and humane?

Best wishes.
