Tomato & Red Onion Tarts


 I’m standing by the frozen section at my local Trader Joe’s one day. I had there puff pastry sheets in my hand and I was mulling it over whether to buy it or not. The woman next to me Saul me looking at the pastry sheets and said, “you HAVE to buy those!”  I believe my face expressed interest but slight doubt. So the woman next to me continued, “seriously, I buy these every single year. I buy six or seven of these. They are so easy and so delicious you have to get them!”

Easy and delicious?!! I’m a middle child and I often feel the need to be the center of attention anywhere outside of my house so I naturally yelled out, “SOLD!”  I then thanked my new acquaintance for her recommendation. And these tasty treats are the result from our quick little conversation. Whoever she was she was spot on - these are simple AND really, really good!


 Herbed butter is where it’s at!! If you’re lazy like me, these are a god send!


Salt your tomatoes with generous pinches of kosher salt.
