I understand what you say, especially with regard to older people and the disabled.

However, we're probably all talking in general terms and it shouldn't be an issue for the majority of us.

A very simple meal would be to put some fresh salmon in the oven and steam the potatoes and vegetables together. You could even steam the salmon on top as well but I prefer it baked or grilled.
You can even buy potatos and vegetables already washed and prepared.

All this takes about twenty minutes and once you adjust the cooker temperature, you can sit back and watch the rest of Eastenders or whatever takes your fancy.

There are numerous other possibilties. Yes, you don't get all the fancy trimmings, sauces, and extra nonsense which you would expect in a restaurant but ... let's face it.. most of all that is unnecessary and just for show. Yes, good presentation etc is a nice extra but you're not getting that with ready meals or burgers either!

If and when you want something extra special, why not go out for a meal in a nice restaurant? Most of us still can afford it now and again.
