In a medium-sized bowl, combine the tomato paste and tomato sauce. Stir until the mixture is smooth and well blended.
Mix in the dried oregano, Italian seasoning, garlic powder, onion powder, garlic salt, black pepper, and sugar (if using). Stir until all the ingredients are evenly distributed.
Taste the sauce and adjust the seasonings according to your preference.
Spread the sauce generously onto your favorite pizza dough before adding toppings.
Notes
For best results, let the sauce sit for at least 30 minutes.
