Carne picada is beef that is thinly sliced, often shaved, and is often used in many Latin food dishes. It is often used in chili and for tacos and burritos. When selecting a beef cut for your carne picada there are several to choose from. You can use regular ground beef, a tri tip beef, or even a round roast. The meat can be sauteed with olive oil, peppers, and onions to make tacos. The most important thing is to be sure to slice it very thin.
