Waste less: tomato paste in a tube

Here's the scenario: you make a dish that requires 2 tablespoons of tomato paste. So you open one of those tiny cans and measure out what you need. Thinking ahead, you save the rest. "I may use it in a sauce or something" you promise yourself. The smartest amongst us will freeze the leftover paste, but most of us will just smack a piece of cling wrap on top on the opened can and call it a day.

Fast-forward to a few weeks later.

You are cleaning out the fridge. Behind the jar of dill pickes, hiding next to the box of baking soda, sits the wrapped can of tomato paste. You take it with a disgusted "eww!" and dare not look under its plastic shield to see what's going on. Out to the trash it goes. What a waste!

The solution is to let go of the cans and to buy tomato paste in a tube. 

You just squeeze out what you need, put the cap back on and voilà! No more waste. And no more breeding ground for bacteria in your fridge. It may look like it's more expensive than the cans, but you'll use it all. And in my experience, it's tastier, too.
