Bring a pot of water to a boil and season it with salt. Add the broccoli rabe or broccolini and boil for 1 minute or until “al dente” (you still want a crunch/bite to it). Drain, spread it out, and set aside. If using the more leafy broccoli rabe, squeeze out any excess water once it’s cooled off a bit.
Add the beans to a medium microwavable bowl and microwave them for 20-30 seconds just to warm them up. Always do this with beans in salads so that they absorb the flavors better.
In a large bowl, whisk together the dressing ingredients until smooth. Add the broccolini/broccoli rabe, warm beans, veggies, herbs, protein, cheese, pepperoncini, and red onion. Toss to coat.
Serve topped with black pepper.
