I freeze food scraps in a Stasher bag, then use it to make veggie stock, which I then feed to my two German Shepherds!
I also use typically discarded green (carrot tops, for example) and veggies to create whole food supplements for my fur babies.
Freeze in season berries and other stone fruit for later use in homemade sorbet, smoothies, and slushy drinks in the summer.
Properly storing produce in the fridge/on the counter to extend longevity. I use a terry cloth Vejibag to keep my leafy greens crisp for weeks!
