Life lesson learned: make sure all your ingredients are ready to go. I have a great big band-aid on my finder right now reminding me that when the onions and garlic are sizzling on the stove, the moment for chopping tomatoes is past. A very brief glance to the pan in the midst of my frantic, last-minute tomato dicing led to my beautifully sharp Wusthof knife slicing a nice little gash into my left pointer finger.
Seriously, people. Just chop the tomatoes, then put the pan on the stove. Your fingers will thank you.
