As with all domestic cooking appliances, you can run one on an invertor but not for long! A 500 watt appliance will need a 600 watt (continuous, not peak) invertor which will draw something in the order of 50 amps from a 12v battery. If you have a 100 amp leisure battery then you will exhaust a fully charged battery in prime condition within one hour, probably much less as you will hit the invertor cut-off voltage quite quickly. If you have a high capacity alternator then you would probably be OK with the engine running but it isn't really feasible for a M/H with a "normal" leisure battery arrangement. Those of you with banks of 10+ high capacity leisure batteries can ignore this - but you know that already don't you?
Help someone out when they're in trouble and they'll remember you when they're in trouble again.
