Preheat oven to 500. Roll pizza dough into a roughly 10-12 inch round shape – don’t worry about getting too precise! Place on a pizza stone or a baking sheet and bake until just turning golden, about 10-15 minutes. Remove from oven.
Quickly spread pizza with the cream cheese. Lay the salmon slices on top of the cheese, and garnish with as much red onion, capers and dill as you like. Cut into slices and serve at once.
