Multi Color Tomato Tart

"3 Ingredient Tomato Tart. For people who need an easy dish that make you look like you know what you’re doing. 😜 Sooooo .... most days around here. My twins turn 5 tomorrow and you can catch a glimpse at their cake in my stories. It’s so warm here that it took forever for me to get the Swiss meringue buttercream to go from soupy to stiff. Almost had a cake-trastrophie on my hands."
