If you want to take it to an even greater extreme here's what I do. Get a 20lb bag of rice, dry beans, frozen vegetables, maybe eggs. The rice lasts me about 2 months and all together can cost as low as about $15-20 a month. You can rotate between making a few different things such as soup, beans and rice with different seasonings, and fried rice. If you want, all of this can be cooked in only a rice cooker. Get used to eating less, your body will adapt.
