Picture pure simplicity: a buttery, garlicky tomato sauce (without meat or herbs), coating tender spaghetti. An easy meal on its own, it would also be a great side dish to a grilled steak for a retro, steak-house meal. Use canned whole tomatoes, not diced. What’s more, you must hand-crush them into the pot. Doing so keeps the somewhat larger pieces intact under pressure, giving the dish a better texture.
