01 - Preheat oven to 475°F. If using a pizza stone, place it in the oven during preheating.
02 - Bring a pot of water to a boil. Blanch broccoli florets for 1 minute, then drain and immediately plunge into ice water to halt cooking. Drain well and set aside.
03 - In a food processor, combine blanched broccoli, basil, walnuts or pine nuts, garlic, Parmesan, olive oil, lemon juice, salt, and pepper. Process until a smooth, vibrant green paste forms. Adjust seasoning to taste.
04 - On a lightly floured work surface, roll out the pizza dough to your desired thickness. Transfer to a parchment-lined baking sheet or a pizza peel.
05 - Spread an even layer of broccoli pesto across the dough, leaving a small border for the crust. Scatter mozzarella and crumbled feta or goat cheese over the pesto. Distribute baby spinach and sliced red onion evenly on top.
06 - Bake for 12–15 minutes until the crust turns golden brown and the cheese is fully melted and bubbly.
07 - Remove from oven and immediately top with fresh arugula and torn basil leaves. Slice into wedges and serve warm.
