For the most part I was able to stick to my budget of $25/week. I ended the 4 week/month long challenge at $104.42. I had a buffer of $10, just in case. I think I did pretty well.
I mostly ate produce (bell peppers, onions, mushrooms, zucchini, potatoes, bananas) and added those things to tortillas, scrambled eggs, etc. I ate very little meat (I did buy a steak and it ended up being enough for two meals). I don't really eat a lot of meat anyway. Mostly when I eat out.
I did eat out more than I had planned on and didn't plan that into my budget. If I do this again I'll consider it, because it does make a difference.
I'd call this a success. I was able to eat well. While I was buying organic produce, I was still eating produce. People complain that it's expensive to eat healthy...it's not. It just takes a little extra time.
