A question about a recipe: chèvre and rapini pizza with red onion, lemon, and pine nuts

Rapini is another name for broccoli rabe as far as I know. It's similar to broccoli but much slenderer and spicier. If you can't either broccoli rabe/rapini or broccolini, I imagine you could substitute broccoli -- the taste will be different, but still good. Best of luck!
