A half cup of sliced banana pieces has 9 g of fiber, 400 mg of potassium, and only 70 calories. If you don't get around to eating those bananas before they become overripe, save them in the freezer for later use. Frozen banana peels turn dark brown or black, but the fruit inside retains its usual color. Frozen banana slices make a great treat on a hot day, or add frozen bananas to smoothies, use them in a banana split or for baking banana bread.
Remove the bananas from the freezer and let them thaw for at least five minutes before you slice them. If they're still too hard to slice, wait another two to three minutes, then try again.
Slice off both tips of the banana, just far enough up the banana to cut through the peel and the fruit's flesh.
Adjust the banana so the that curved side faces down, then slice through the banana lengthwise. If slicing along the entire length of the banana is too difficult, slice the banana in half through the middle, then slice through each half lengthwise.
Use your fingers to peel the banana peel away from the still-frozen banana.
