I thought this might be a good topic since everyone has such good advice to share. List your favorite "I had no idea" tip.

Here's two of mine:

I seriously had no idea that you didn't need to precook lasagna noodles. Lifechanger for me, since lasagna is now so easy to prep on the weekends and pull out and bake later in the week.

I also had no idea that you could muffle a doorbell with a flat refrigerator magnet.
