I asked a question about healthy afternoon snacks that are as convenient as cookies and chips. In my house, I know that if a healthy alternative isn't right there, ready to go and staring us in the face, we'll reach for the junk food snacks. Phil listed some snack foods that are healthy, but not all of them are exactly frugal. He went on to suggest healthier chips, made at home.
The basic idea is to spray a baking sheet with nonstick spray (like PAM), then bake thin slices of banana. This sounds like a tasty, easy, frugal idea to me.
If, like me, you'd like more details instead of just winging it, here's one recipe. In searching for that, I also read that the recipe can be made with plantains instead of bananas, and can be seasoned to be savory instead of sweet. All good ideas, I think.
Let me know if you've ever tried making baked banana chips at home!
