Add 2 Tbsp of olive oil to a medium pot and heat it up. Add half a cup of chopped onion to the hot oil and swirl often until the onion is tender and golden (about 5 min). When aromatic, add the minced garlic and stir for one minute.

28 oz of smashed tomatoes, 1/2 tsp of oregano, 1/2 tsp of salt, and 1/4 tsp of pepper should be added. Lightly boil, then lower heat and simmer 15 minutes with a partial lid on.

Finally, turn off the heat and whisk in 1 tablespoon finely chopped fresh basil.
