Just smash up the avocado in a bowl, apply the mashed avocado to wet or dry hair, let it sit for an hour – then wash your hair like normal! Your hair will be super soft and ultra smooth.

If your eggs have gone bad, instead of tossing them in the garbage, crack them open, put the whites and yolk down the drain, and use the eggshells in your garden. Crunch them up into small pieces and scatter them throughout the garden. They’re rich in calcium and minerals which are helpful in growing strong and healthy plants and veggies.

You certainly wouldn’t want to eat stale bread on your sandwich but it doesn’t mean that you can’t eat it all. Just use it to make croutons or breadcrumbs! Cube the bread and spread a little olive oil, salt, and pepper on the pieces then pop in the oven until they’re nice and crispy. Or, pulse the bread in a food processor for yummy homemade breadcrumbs.

How many times have you been baking, reach for brown sugar, and find that it’s hardened into a seemingly unusable brick.

Just because your spinach or cilantro wilted, doesn’t mean you need to compost it or toss it in the garbage – hang on to it! Just put them in a Ziplock or plastic container and freeze them.

Is the milk in your fridge smelling a little less than fresh? If so, it’s actually a great substitute for buttermilk when cooking or baking (just be sure it hasn’t started to curdle).

Adding copper, though, neutralizes the sulphur smells and renders your wine palatable again.” Just be sure the penny was made before 1982 when copper was used.

One of the great things about hard or stale bread is that it’s easy to ‘cover up’ its staleness with some eggs and cream. According to Simple Dollar, all you need to do is:

“Take some pieces of dry bread and dip them into beaten eggs and layer the bottom of an 8″ by 8″ or a 9″ by 13″ pan that’s lightly oiled or greased. I usually use six eggs for a smaller pan and a dozen for a larger pan. Add some toppings above the bread – cooked bacon or sausage, perhaps, or onions and green peppers that are chopped – and pour the remaining eggs on top. Sprinkle some cheese on top and bake at 350 F until the eggs are cooked through.”

When bananas become super soft, they become extremely sweet – almost too sweet. And the texture isn’t as desirable anymore. But what old bananas are perfect for are banana pancakes and that sweetness mixes perfectly with the batter. Just make pancake batter as usual and toss in slices of the overly ripe banana. It makes for a delicious breakfast, plus, you didn’t waste your banana!

Vegetable soup is a great option if you still want to use veggies that just aren’t quite as crisp as you’d like them to be anymore. Since the vegetables soften while simmering in a broth, you’ll never notice the difference between a fresh zucchini and one that was a few days past its prime.

Wilted herbs like cilantro, mint, or parsley can still be used, but you’ll need to dry them out first. hang the wilted herbs in a dry area with direct sunlight. Once they’ve fully dehydrated, pulse them in a food processor to create your own seasoning mix. Get creative by combining herbs, salt, pepper, or whatever your palate tells you to!

Turn stale tortillas into a yummy family dinner. Here’s the recipe from The Simple Dollar:

“Just brush the insides of a 9″ by 13″ pan with olive oil, then take a few tortillas, spread refried beans on one side, and layer the bottom of the pan with them. Add a thin layer of cheese, a thin layer of vegetables (salsa is good here, as are diced tomatoes and onions), and maybe another thin layer of cooked beans if you’d like (I like black beans). Then repeat all the layers, starting with the tortillas. Do this three times, then cover the top with a bit more cheese and bake it all for 30 minutes at 350 F, then let it rest on the table for 10 minutes or so before serving.”

According to Epicurious, “to add heft to your bowl without thickening the entire soup, simply place a thick, toasted slice or two of stale bread at the bottom of your soup bowl.
