Eccles, at our holiday home I only use the microwave. Ok, so it's an all singing all dancing one with oven and grill but I do tend to mainly use only the microwave part.
Ive found the best way of using it is to make one pot type meals, just as you would with an oven. They don't come out quite as nice but are still very edible, and as you're such a good cook anyway I'm sure you can come up with lots of lovely one pot type things, much nicer than I do.
I make spag Bol, chilli, any kind of casserole you can think of which involves any and all veg and meat. And fish too. I also have a small plastic bucket type thing with a clip on lid for a few £££s to do rice or pasta in the micro, which is very successful, I got it in Robert dyas but I'm sure they have them in lots of places.
Personally I wouldn't bother with ready meals to shove in, they're nowhere near as nice or healthy although useful in an emergency.
You've got loads of imagination regarding food, I'm sure you can do lots of lovely tasty things once you get your head round it. If you have any great successes I'd love to hear about them ;)
