Yeah, it's not a good idea to live on processed foods...
For the longest time, I barely touched the microwave. Only ever to really warm up pre-cooked foods and even then I barely did because I don't like eating left-overs.
Aldi (a supermarket in UK) do some absolutely lovely steamed salmon with herbs and chilli. Pop it in the microwave for 6 minutes and it steams itself in the bag. It's great with veg and potatoes.
My boyfriend has opened my eyes to microwave cooking, I always boil my fresh veg but he always microwaves it and it tastes just as good. You can part bake things in the microwave too then stick them in the oven.
I cook my own meals when possible. Since moving back home and considering my mum no longer works, she usually does the cooking but I'm more than capable and always make them something when they fancy something different.
I don't watched Kitchen Nightmare but I think Ramsey puts on a bit of a front for the camera...
As for being picky, yes and no. I have no problem going out for something to eat because I usually find something I like. I prefer my food well cooked (veg and cornflakes mushy, crispy bacon etc) and lots of fat just puts me off.
I don't like anything hot and spicy, chicken on the bone, pizza, anything too cheesy, anything cheese and onion, peppers, chillies, spinach, cabbage, cauliflower, lamb, pork chops, beef, steak, burgers...
I'm a bit of a pain to cook for.
