Recently, I discovered the most amazing cooking hack ever. EVER! (Thank you Martha Stewart youtube videos.) I have no doubt that this is going to save you a ton of time.
Here's how it goes...
You're going to need a long serrated knife, two lids (just use two of those plastic lids from your tupperware), and tomatoes.
2. Place tomatoes in between the two lids and cover with the 2nd lid.
3. Run your knife through the center of the two lids. I used a long bread knife.
4. Viola! You're ready to use those tomatoes on the stove in a pasta or in a salad.
Super simple, but pretty genius. Thanks again, Martha!
