It is a nice house canella and I think it is reasonably priced. You may just be on the market at the wrong time and you have been a bit unlucky with that.
Did you hear back about the woman who had viewed 3 times? That does sound as though she is likely to take it.
LOL deb, I veer off healthy food ALL the time, unfortunately, partly because I'm a lazy cook.
Not sure I'd want him to acquire a taste for regular junk food though. Agree with canella, mashed potatoes with cream and even big chunks of butter thrown in and fatty meat etc might be better. Then if he should ever get the opposite problem, being overweight, it would be easier to drop cream/butter and move from fatty to leaner meat.
Does he like salami? How about banana milkshakes with Vollmilch, some cream, big chunk of vanilla ice-cream. You can then just move to a vanilla yoghurt-banana smoothy when his weight is back up.
Macaroni cheese with lots of cheese in it? Pizza with cheese, salami, some veg and so on for him and a leaner version for everyone else?
