St. Anthony the Abbot, the Egyptian Early Christian and founder of most organized monasticism, is generally depicted with the attribute of a pig, because he once saw the devil in the form of a pig.
(He got bugged by lots of demons, but generally paid them no mind. He compared demons to mosquitos – always around, always annoying, but not a real danger.)
In the usual humorous style of picking patrons, the presence of the pig attribute led to St. Anthony (who ate no meat as part of his ascetic practices) becoming the patron saint of pigs, butchers, and bacon curing, as well as all livestock and animals.
Other patron saints of butchers include St. Adrian (a Roman soldier who got butchered during his martyrdom) and whatever saint was patron of the local butchers’ guild parish. 🙂
But of course the patron saint of cooks, and specifically grill cooking, is St. Lawrence, the Roman deacon who was executed on a grill. He famously quipped, “This side is done. Turn me over and then you can eat!”
