You can cook pretty much anything in a microwave -
Eggs - poached, scrambled, omelettes
Rice, pasta and noodles can all be cooked in microwave
All sauces can be cooked in microwave but you could easily batch cook so you can sauté off garlic, onions etc you don't need to freeze whole meals, just sauce bases would keep you going for ages
I'm veggie but my mum isn't and she cooks meat and fish in the micro all the time! Fish especially comes out lovely I'm told
All veg can be microwaved
There are TONS of tinned meals that can be microwaved even as a veggie there's various pastas, curry, chilli...
Cous cous and other very small pasta and even quinoa can be cooked simply steeped in boiled water
If you get toastabags for the toaster you can make not only toasted sandwiches but you can also use these to cook breaded items (fish or veggie fingers, nuggets) pastry snacks (I LOVE a cheese and bean pasty cooked this way), bacon, sausages (slice in half length ways to lessen thickness but yummy!)... all sorts
And as it's summer (checks outside window and calendar - they don't quite meet!
) yes salads, wraps, sandwiches, picnic/buffet foods (quiche, tarts, sausage rolls, mini scotch eggs, cocktail sausages, olives, cold hard boiled eggs are everywhere now!, anti pasti type items...)
You'll be fine
