Can't cook huh?
I love cooking.
Try herbs like dill, oregano, basil, mint even.
Trick is not to cook vegetables too long or you get it too mushy and kill a lot of the flavour.
The microwave is so uncreative.
Stuff like broccoli and cauliflower can be boiled or steamed. Then you sprinkle your dill on after you drain it. Cut it in bits and taste it as you are cooking to make sure you don't overcook it.
You can grill for your more solid veg like carrot or pumpkin. You control the amount of cooking by how large you slice the bits. Large chunks will be too raw in the middle with the outside overcooked. Drizzling olive oil and rubbing it around them stop it from burning.
Leafy stuff can be pre-blanched very quickly (maybe a minute or two in boiling water) then you can grill or shallow fry them as hot as you can make it and add your herbs in then.
It's all about understanding how to combine a couple of different types of vegies to make a meal. You can cut cabbage really thin, blanch in hot water, drain and then shallow fry with raw carrot (cut thin also) and add a splash of balsamic vinegar and a herb like thyme. Let the vinegar reduce while your stirring it around. Turn it down and cover for a minute. This is sort of like braising it.
