Things Taste Awesome

Onions brown in about a minute and they make food taste like you've spent some real time on it. I chop up a whole onion and store it in the fridge in a ziploc bag. Since they're already chopped they can just be added to whatever (savory) thing you're cooking/warming up. For example:

Can of soup: Before pouring the soup in, cook a small handful of the onions with a little oil/butter in the pot.

Scrambled eggs: Same thing, but with eggs.

A lot of preparation can scare me away from doing things. This isn't perhaps a huge time-saver, but if there were not pre-chopped onions on hand I wouldn't do it!
