Once again, the Bible leads us to the correct answer. If God could reveal himself to Moses as a burning bush that was not consumed, then it stands to reason that a hot burrito would give him no problems. Oh ye of little faith.
Yes, but obviously the bush wouldn't be consumed, unless God was a goat or some other shrub eating animal? You can't draw any conclusions about reheated mexican food from shrubbery.

What you CAN conclude though, is that if God is doing some gardening, and He has hedge clippings to get rid of, He had better not start a bonfire, as presumably it would burn for ever.
