I believe there’s no such thing as bad pizza. But the thing that makes a GOOD pizza is the sauce. You can throw on whatever cheese and meats and vegetables you’ve got, but it takes a certain level of mastery to find the right tomatoes, textures, seasonings, and ingredients for the sauce.

Or, conversely, not sauce; a good olive oil brushed on a thin crust, sprinkled with a tad of dried oregano (fresh, if you want a Caprese vibe), and prodigious amounts of freshly crushed garlic can be what puts a pie over the top.
