Prep Time: 30 minutes
Bring a large pot of salted water to a boil over a high flame. Blanch the broccoli rabe for 3 minutes and then remove it to a large bowl filled with ice water until cool. Gently squeeze out any excess water and set aside.
Preheat the oven to 450 degrees. Coat a baking sheet or pizza pan with a thin layer of olive oil or a dusting of cornmeal. On a clean working surface dusted with flour, gently stretch the pizza dough to fit your pan, roughly a 12" circle or 10" x 6" rectangle will do. Gently place dough in the pan.Spread the pesto onto the dough evenly, leaving room for a border crust. Top with the burrata and then the broccoli rabe and tomato. Season with a pinch of salt and place in the oven until the cheese is bubbling and the crust is golden brown. Garnish with the oregano and cut into 4.
