I TRY to buy organic, but I totally agree it can be really expensive! About half of my produce is organic, and I guess that is better than nothing. Sometimes if you go to Whole Foods or Wild Oats, and ask the produce person for some "almost bad" fruit, they'll sell it to you at a discount. I got a whole case of organic bananas for 25 cents /lb, and most of them were good! Just throw them in the freezer and they make a wonderful dessert!
Greens really aren't too bad. You can get a huge bunch of organic greens, like kale, beets, spinach, etc, for about $2 at the Wild Oats near my house and that makes for a glass of green juice for me. Of course I add a few carrots and a cucumber in there to enhance the flavor, but if you substitute that for a light meal or snack that shouldn't be too much. I know that as far as making gormet raw desserts I have spent upwards of $20 in ingredients just to make ONE dessert, and THAT is just way too much! lol. $2 a bunch can be bad for greens sometimes, but if you look for the biggest bunch you can find, sometimes you can get almost your money's worth, lol.
Oh I really think you should give juicing another go! If you buy one of those non-spinning juicers (like the ones that crank your veges) you can do so much more than only juice! You can make nut butters and even "ice cream" (Just process the frozen bananas, or try frozen mangos - tastes just like mango sorbet!). Also farmers markets give excellent deals, but sadly the warm weather is coming to an end (in my area at least).
Oh! Also if you buy veges or other produce by the case sometimes they will give you a 10% case discount! I ususally just try to catch the sales though.
Oh and did you know that Larabars are organic and raw? I read it in Body + Soul magazine! I tried one and they are very heavy and filling! If you sometimes feel empty and poor because the cost of the organic produce, a Larabar might help you fill up a bit, and they aren't too bad. Though they aren't the most healthy thing, consisitng a majority of nuts and dates, they are ok once in a while. I actually ate 3 in a row once I was so hungry and they gave me an upset stomach, so be careful.
