I have a question about the recipe "chèvre and rapini pizza with red onion, lemon, and pine nuts" from The Dog's Breakfast.
Are you channeling your best self with this comment? (If you're not sure, check out our Code of Conduct.)
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!
