My number one brekky is toasted muesli. Find a place where you can essentially 'make your own' - the place I go to has a 'muesli wall' and you byo container and just fill it up with different oats, bran, fruits, seeds, nuts etc. However - if you can't do that, there are some pretty good ones from Coles/Woolies (just watch out for honey!)
I normally just have a sandwich for lunch - but that's because I'm boring.
Dinner - well, tonight I'm having tofu, vege and noodle stir-fry in satay sauce. Last night we had pasta and vege ragout. It depends a lot on what we feel like and what we've got in the cupboard! As long as you get a good mix of veges, pulses and beans, you should be pretty much right.
ETA: Good luck, and congratulations.
