A lightsaber won't work as a spit, I'm afraid. That's an accident waiting to happen:
anonymous Jedi 1 (points to meat on a lightsaber) : Hey, buddy, come try this tasty shishkebob!
anonymous Jedi 2 (leans over meat): Shishkebob, huh? Where's the stick?
anonymous Jedi 1 (slaps his head): Oh. Forgot to turn it on...
ignites saber, which impales both the meat and his friend's head
That's how Palpy started the Purge...
