Bring a large pot of water to a boil for the pasta.
Heat a skillet with a lid over medium-high heat with olive oil, 3 turns of the pan. Add garlic and swirl; then add cherry tomatoes and season with oregano and red pepper flakes. Stir in basil to wilt and season with salt. Cover and cook 15 minutes to break down tomatoes, giving the pot a shake now and then.
