While the oven is heating, prepare the pesto. Bring a medium pot of water to a boil. Add the peas to the pot and cook for 5 minutes or until bright green and heated through. Drain and rinse with cold water.
In the bowl of a food processor, pulse the peas, basil, garlic, and pine nuts together until they are minced. Stream in the olive oil while the food processor is still running and puree until creamy and well-combined. Add the parmesan cheese and lemon juice to the food processor bowl and pulse until they're fully incorporated. Season to taste with salt.
Grease a 14-inch round pizza pan with a light layer of olive oil. Using your hands or a rolling pin, pat the pizza dough into a 12- to 14-inch circle on the pan. Spread the pea pesto over the dough in an even layer, leaving a 1-inch border for the crust. Sprinkle evenly with the artichoke hearts and the mozzarella slices. Place the pan in the oven and bake for 10-12 minutes, or until the bottom starts to look golden brown. Remove the pizza from the oven and sprinkle with red pepper flakes and black pepper, to taste. Let rest for 5 minutes before slicing.
Notes
Feel free to substitute your favorite spring veggies for the artichoke hearts. Asparagus and roasted red peppers would also be great here!
