Life is already stressful. Eating is essential—no reason to feel stressed out about it. When the budget is tight, and you have to throw food away because it’s spoiled, it is like throwing money away.
Put those scraps in a bag and keep them in the freezer. When the bag gets full, drop all the leftovers in a pot with water. Then season the stock to your liking.
You can rehydrate stale bread by quickly putting it under running water and in the oven at 350 for 5-10 minutes. You can also turn your stale bread into breadcrumbs.
Our favorite is green onions. Instead of throwing away the scraps just plant the bulb of the green onion in dirt and it will grow back a few weeks later.
Leftover rind from Parmesan cheese? Keep the cheese rind in the fridge or freezer, and toss it in soups, sauces, or stews for an extra oomph to your dishes.
