Make the pesto: In a food processor, add the kale, pecans, lemon juice, garlic, salt and several twists of freshly ground black pepper. Turn on the food processor and drizzle in the oil. Process until the pesto reaches your desired consistency, stopping to scrape down the sides as necessary. Taste and add more lemon, salt or pepper if necessary.
Preheat oven to 500 degrees Fahrenheit with a rack in the upper third of the oven. If you’re using a baking stone or baking steel, place it in the oven on the top rack. If you're using my dough recipe, prepare dough through step 4. If you're using store-bought dough, check the instructions of the package. It might need to rest at room temperature while you work on the pesto.
