Yes, there's a lot of very PA critiquing of other people's food.
Poster A: we're going to have sausage, mash and beans.
Poster B: Wow! I didn't know anybody still ate things like that. I suppose there's still a long way to go with health education. A few simple tweaks would make that meal a lot better, OP. Instead of sausages, you could roast an organic chicken breast (skinless, of course), no salt or pepper of course, and definitely no butter or olive oil! You've got to think about food poisoning as well as nutrition, so cook it for about two hours to be on the safe side. You don't want to overload the kidneys with protein, so one chicken breast between four people will be fine. I find when cooked like this, nobody wants more than that, anyway! It's just a matter of relearning what's a good portion size. I personally use a baby bowl for my own food as I find that helps to keep my inner glutton 
under control!
Then instead of mash and beans, serve a mix of veggies (organic again, goes without saying really) that you've steamed for 30 seconds, which is all they ever really need, or just raw. So much better for veggies still to have a bit of bite. We have a minimum of seven different veggies at every meal, including breakfast, each one a different colour, which is absolutely essential or else you die a horrible death within days. It really doesn't take long once you get in the way of it. I think I only spend seven hours a day prepping veg.
Of course, when I say veggies, I'm not including potatoes! Potatoes are a rubbish food, they really ought to be banned. So much better to fill up your stomach with lots and lots of spring water (not tap of course, that's really dangerous).
We don't bother with sauces because they tend to be too salty. After about ten years of cooking with no salt, you don't notice any more that it's not there.
Hope this helps!
