Oh, I'm a sucker for #3! Seasoning is EVERYTHING.
I cook the food for my little boy with spices and they taste like I did put salt on them - actually, they taste even better! Since then, I started cooking most of my dishes with mostly spices and just a pinch of salt if needed. And also the #6! If I'm using ingredients that already have salt in them, adding more salt is usually pretty useless!
