I agree, only hubbie and I here, admittedly we do have very large roast dinners, but we'd do that size pork on a Sunday and have some left over for sandwiches ect.
I think I understand why the older ones snack so much after seeing her portion sizes. I work on produce in a supermarket and it's VERY hard work, Jamie will be needing plenty of energy. Maybe if the dinners they are making was better planned out they wouldn't snack (that she moans about all the time. Remember the locked cupboard?) so much.
She's not going without is she, we can tell that by the amazing weight loss she's having on slimming world...oh wait!
