Cooking beef in a microwave

The gas has been shut off in our La Mongie flat. V annoying. The company say they sent an email saying I should phone them, but I never received it. They cannot come to reconnect until the 26th Dec. Will make Christmas dinner tricky. We plan on taking up our induction hob and mini oven so hopefully will work out ok.
We only discovered it when we got up there one evening planning on making a quick pasta dinner with gorgonzola, pasta and beef. I ended up cooking each bit in the microwave and them putting it all together. You wouldn't think microwaved steak would be edible, but I heated up oil in a pyrex dish for 7 minutes on high and then tossed the chopped up and salted steak in to the hot oil and put back in for a minute. It worked out really well!
