Green things...
Fresh herbs. I guess dried herbs, too, because where would cooking be without them, but there is something so refreshing about fresh herbs.
Money. While we have never truly been without, we've also been in the position of not having enough money for basics. While we aren't in the category of having money to spend willy-nilly (for example, there are no new cars here or multi-week long trips to Disney) we have enough income and savings to know that we can weather the occasional emergency (like this week's $2500 car repair) without having to resort to ramen noodles for dinner for the next month.
The color green itself. For a long, long time it was my favorite color, including all its shades. Right now my favorite color family is probably purple, but I still love green.
