Here's What You'll Need
skirt steak, olive oil, cilantro, garlic, lime, orange, jalapeño, cumin, salt, chili powder, pepper, red wine vinegar, shallot, red pepper flakes
Combine steak marinade ingredients in a large container or Tupperware. Add skirt steak, then cover tightly and refrigerate for up to 1-2 hours.
When ready, preheat broiler to high. Place steak on a parchment lined baking sheet. Broil on high about 3-4 minutes per side, until medium rare, about 125-130 F.
Combine all chimichurri ingredients together in a measuring cup, then whisk to combine.
Before slicing, allow steak to rest for 10 minutes. Thinly slice across the grain, then serve immediately with cilantro chimichurri and chopped onions.
