Spaghetti alla Gricia
One of the 4 quintessential 'primi' from the Lazio region in Italy, this pasta is beautiful in its simplicity with soft guanciale and tangy Pecorino cheese. No onion, no garlic, no oil - this flavorful dish gets its character from slowly sauteeing the guanciale and then creating a creamy sauce with the pasta water and a bit of Pecorino Romano before tossing with thick spaghetti. With only 4 ingredients, this is also a quick meal when you're in a rush.
If you cannot find guanciale, you can use pancetta instead.
