People grossly under or over estimate what a serving is.
When I see people say that they have a "teaspoon of oil" on a salad, I am like, YEAH, RIGHT! That's less than a 1 second splash!
I eat more vegetables than anything else on average. I've been eating lots of fruit lately though.
On a daily basis, I try to eat vegetables first, beans and legumes and protein rich products (including soy or seitan) and fruit next, then fat-rich foods (including nuts and seeds) then starchy foods (pasta, rice etc.) and lastly sweets.
