My son's a relatively picky veggie eater so I'm resorting to subterfuge here. He loves sweet potatoes and I've managed to convinced him this is them, just mashed. He loves it! Now besides fried onions and raw carrots I've at least got him to eat some squash!
I have to say my dad was the only member that could make a fantastic meal. No matter how late it was, at least 4 kids would show up looking to be fed. The easiest and most elegant thing he ever did was leg of lamb. I've given this to my ex-mother-in-law and many of her friends!
