Does she do any of her mum's recipes in this series? I know Doria probably is camera shy, but it would have been nice for MM to do something to connect to her roots through cooking/hosting a relative.
She did that ridiculous "making toast" thing pre-Harry, when she talked about her grandma's apple butter, but rather than showing us how to make that, she just made the toast, told us not to be scared of making the toast, and then spread some on.
She's also talked about surviving off $4 salads.
She also went to 2 very high priced private schools, which no doubt provided some lunchtime food options of decent quality.
She's also talked about spending her after school time on the set of Married With Children with her Emmy Award winning, high earning father, who no doubt had the means to buy her a decent restaurant dinner if required, so that's not going home alone and eating TV dinners.
It's anyone's guess!
