Gather and prep all ingredients - mince garlic, get enough chili flakes/crushed red pepper and pan fry meat slices. And below is the type of store-bought beef slices we usually use. You can also use pancetta or similar meat slices with extra fat.

To prep meat slices, pan fried them, then cut into thin strips and chop into bits. See pic below.

Next, cook pasta noodles in a pot with enough water, some salt and some oil. We are going to cook this al-dante, as to be still firm when bitten. Check your pasta when cooking. Few minutes before pasta is about done, to al-dante, sauté garlic in Olive Oil for a minute and then add chili flakes.

Sauté until garlic is lightly brown and by now, pasta noodles should be ready. Transfer pasta using a tongs to the pan, reserving few tablespoons of the liquid in case it's needed later. Toss pasta in the pan and sprinkle some salt (use as needed). Toss until well-combined. Add few tablespoons of reserved pasta liquid only if it's very dry. Taste and adjust accordingly. You can add your pan-fried protein now or use it later for toppings along with grated cheese/grated parmesan cheese.

Garnish and best served warm.
