In a small sauce pan over medium heat, bring all ingredients except the cheese and lemon juice to low boil. Remove from heat and stir in the cheese and lemon juice until cheese completely melts into the sauce.
For the Pizza:
Roll dough out into a large circle and place onto a large cookie sheet or pizza pan. Spread the top evenly with lemon cream sauce, then top with mozzarella cheese, lemon slices, artichoke hearts, lemon pepper chicken, and feta cheese.
Bake at 400 degrees for 18 to 25 minutes. Dough should be completely cooked in the center and cheese should be melted, if not add more time.
When fully cooked, let sit for 5 minutes before slicing. Then top with pieces of arugula lettuce.
