Pumpkin seeds are mentioned, but pumpkins themselves are fantastic as well -- they make for some really great soups.
Also, I'm certainly not one to knock coffee, but tea is much better in terms of bang for the buck. I buy loose-leaf jasmine tea from an Asian grocery store, and get a month worth of tasty drinks for less than two bucks. It's healthier than coffee to boot.
I will fully agree that tea is better for you than coffee and I am an avid tea drinker, having several varieties in my pantry but nothing, and I mean _nothing_ beats a nice home-brewed french pressed cup of coffee.
But maybe I'm bias because that's my morning routine. One wonderful cup of that gets me going. The aroma is what wins me over mostly.
Agreed re: tea - I get mine shipped from the other side of Australia (because I cant get what I want locally), but even factoring in postage costs its still significantly cheaper than other drinks (except tap water)
If you want tea, you can make some out of barley or brown rice. The stuff is pretty popular in Japan and Korea. I don't usually like most teas, but barley tea can be good.
If you're in the US and want to get some good tea, I highly recommend the Upton Tea Company (http://www.uptontea.com), they have excellent teas at a wide range of price points.
I drink gyokuro and unfortunately I've been unable to find anything local here in Perth that is decent.
I know it can be expensive when compared to other teas, but I'm able to get about 4 infusions out of every serving so the price is much less than originally thought, plus its still significantly cheaper than other options (eg soda drinks)
It can be, theres varying grades in gyokuro depending on the region its from.
I generally go for a lower to middle grade of gyokuro, My palette isn't developed enough to tell the difference (heh) but I pay about $22 Aus for 50g (inc postage) which does me around 120-130 cups of tea.
I have found it can be cheaper to buy it directly from Japan, but I'm not entirely sure if I want to go through the hassles of importing it as I've always had troubles with Australian customs.
