Pesto made with broccoli rabe is pretty popular and it is also super nutritious. You can serve the pesto as a dip or spread for bread instead of as a sauce for pasta. I followed a recipe from Mario Batali’s Molto Gusto. If you follow the link, you will not only find the recipe, but a clip of Mario demonstrating its preparation along with that of two other pasta recipes (pasta with pureed red peppers and goat cheese and pasta with Swiss chard).
The original recipe called for orecchiette pasta, but I substituted farfalle and added in some heirloom grape tomatoes. Later, I served leftovers as a salad, with the addition of more blanched broccoli rabe and some cannellini beans.
The pesto is exceptionally good. I made twice as much pesto as I needed for the pasta, and I have been enjoying leftovers spread onto challah along with lemon chummus.
