Preheat oven to 375.
Warm the water and pour it in a large bowl; whisk in the yeast until completely dissolved.
Add in olive oil and flour.
Stir with a wooden spoon until it all comes together and a ball of dough is formed. You may need to use your hands.
Cover with kitchen towel and set in a warm place for 15 minutes.
Line a baking sheet or a pizza pan with foil and spray it with cooking spray.
Transfer dough to a lightly floured surface and knead for 3 minutes.
Spread pizza dough on the prepared pan, using the palm of your hands and fingers to stretch it out to about a 1-inch thickness.
Bake for 10 minutes.
Remove from oven and let cool for 5 minutes.
Spread the cream cheese on top of the pizza crust.
Separate the artichoke leaves and layer over the cream cheese; set aside.
Heat olive oil in a frying pan and add the spinach.
Season with salt and pepper; cook until just wilted.
Mix in the minced garlic and remove from heat.
Spread the spinach mixture on top of the artichokes.
Top with cheeses.
Bake for 15 to 20 minutes, or until crust is browned and cheese is melted.
