To help avoid food waste at home, think like a restaurant chef. Use overripe bananas by mashing them up and mixing them in with pancake batter to make delicious treats for breakfast. Leftover coffee can be frozen in ice cube trays to use in iced coffee drinks. And even leftover oil you've used for frying can be strained through a clean coffee filter to be reused when cooled. Your frugality will make you more creative with your cooking.
