One of the biggest issues people have with eating "real food", is how expensive it is. Lately I've been thinking that some of the foods we eat are actually pretty inexpensive.
sprouts - A bag of alfalfa seeds only costs a couple dollars and lasts a long time. Sprouting is an easy frugal way to boost your nutrition.
kefir - Making your own kefir is inexpensive as well. We use kefir in smoothies or in baking instead of yogurt or buttermilk. Kefir = milk + kefir grains. A gallon of milk is much cheaper than a gallon of yogurt or a gallon of buttermilk.
granola bars - This recipe makes 18 granola bars, waaaay cheaper than buying boxes of them at the store!
tortillas - Just 2 cups of flour and a little bit of oil makes delicious homemade tortillas. Whipping these up and using my tortilla press takes no time at all.
beans - Rehydrating dry beans is actually pretty easy and quite cheap. We enjoy beans and rice, pinto beans in tortillas, or even black bean brownies. Black bean burgers are on my list to try next.
I've found that "making my own" granola, granola bars, tortillas, etc is often cheaper. I simply plan for a bit more time in the kitchen and regularly make these things instead of buying them. Now that I have the recipes down, it doesn't take long to do. This also allows me to buy the ingredients in bulk at cheaper prices and streamlines my grocery list. (Instead of buying cereal, granola bars, tortillas, etc, I buy a huge box of oats and other staples.)
Have you found other good ways to cut your "real food" budget?
