Step 1

Place the garlic, jalapeño and cilantro in a food processor or blender and process until it forms a paste. Transfer the mixture to a bowl and whisk in the lime juice, orange juice, vinegar and olive oil. Season with salt and pepper to taste.

Step 2

Place the steak in a large dish and cover with the marinade. Cover with plastic wrap and let the dish marinate in the refrigerator for an hour.

Step 3

Preheat a grill or grill pan to medium-high heat. Remove the steak from the marinade and cook for 5-10 minutes per side (depending on the thickness of the steak and desired doneness).

Step 4

Let the meat rest, then slice against the grain and serve.
