The taste of fast food is what draws people in, right? Or is it the smell? We make a lot of decisions on what something smells like. Want to increase your family's appetite? Make something that smells "good" and they'll eat it.
Fast food restaurants cook onions on a grill to get the smell out there... why not you? Or... you could just make plain old good "fast food" that they'll eat!
Fast food is not always fast, but it's nearly always faster to cook at home than to drive to a fast food place, put in your order, wait for it, pay for it, drive home and finally, eat. Save time? Nope. It does save some energy, if you don't mind spending the extra money for gas and food.
Frugal living isn't about spending money, though. It's about saving it and if you can save time, too, why would you spend both money and time for something that's not good for you?
If you're "too busy" to cook, you're better off to buy boxed or frozen meals than to go to a fast food place. Make some food ahead on your days off. There are ways to eliminate the fast food habit; we just have to work at it.
You'll be money, health and time ahead if you do that.
Do you make your own fast food?
