Speaking hypothetically, not to what the Pope did, were I planning a general outreach meal for a church here in Silicon Valley, I would probably serve chicken, turkey or fish. Muslims and Jews don't eat pork, and non-vegetarian Hindus don't eat beef. I might even do vegetarian dishes in a separate part of the kitchen using utensils and pots that have never been used for meat for strict vegetarian Hindus. If outreach is the purpose, then serving pork or beef would be incompatible with that purpose.
