Preheat the oven to 500ºF.
Roll out the pizza dough on a lightly floured surface until it is roughly 12 inches wide and 1/4-inch thick. (See Notes.)
Invert a baking sheet and sprinkle it liberally with cornmeal. Transfer the dough to the baking sheet then brush the dough lightly all over with olive oil.
Combine the ricotta, parmesan cheese, garlic and parsley. Season the cheese mixture with salt and pepper to taste.
Using a vegetable peeler, shave the asparagus length-wise into thin ribbons.
(There's no need to remove the tough ends first, as you can use them to more easily grip the asparagus as you peel them. Just make sure not to shave off any of the tougher part.) In a small bowl, toss the ribbons with 2 teaspoons of olive oil.
Spread the cheese mixture all over the pizza, leaving a 1/2-inch border around the edges.
then evenly distribute the asparagus ribbons on top of the cheese.
Bake the pizza for 10 to 12 minutes, rotating it half-way through, until the crust is fully baked and golden brown. Remove the pizza from the oven to a cutting board, drizzle it with fresh lemon juice, and slice and serve.
The pizza dough can be rolled into any desired shape, including round, rectangular or free-form, for a more rustic look.
You can use a pizza stone in place of the inverted baking sheet.
Oven temperatures and positions may vary, so make sure you are baking your pizza on the middle rack and check it frequently.
