Preheat the oven to 475℉. Line a baking sheet with parchment paper. Lightly oil the parchment with ghee, coconut oil, or rice bran oil.
Combine the eggs, oil, lemon zest and juice, parmesan, anchovies plus oil, garlic, mustard, basil, and salt in a blender or food processor. Blend until smooth.
In a large bowl, combine the lettuce, kale, spinach, onion, and pine nuts (if using). Toss with the dressing.
Stretch the pizza dough by hand or with a rolling pin to fit the baking sheet.
Brush the crust with the ghee and bake for 5 to 8 minutes.
Remove the crust from the oven and top with a layer of salad. Bake for another 5 minutes or until the bottom of the crust turns golden brown and the salad looks slightly wilted. Serve garnished with basil and pepper.
