Roasted Heirloom Tomato, Zucchini + Caramelized Onion Tart

I had my favorite neighbors, Rick and Gary over Saturday night for wine and apps.   We don’t like to do a sit down dinner but just have a few nibbles with our wine.  I went the Farmer’s Market that morning and wanted a few light,  fresh and easy Summer appetizers.  I also made a white bean dip which I will share later this week!  This tart was so yummy!  The combination of the roasted tomatoes, caramelized onions, tangy dijon mustard, and creamy burrata was such a good combo!!  It is great served room temperature so perfect for Summer entertaining!  You could eaaily make this a meal and serve it with a pretty green salad.  Enjoy!
