Cook the rice. Start your preferred rice so it's ready when the steak is. Keep it hot and fluffy; this is the bed that catches all that chimichurri goodness.
Make the chimichurri. In a bowl, combine parsley, cilantro, garlic, shallot, red pepper flakes, oregano, red wine vinegar, and olive oil. Season with salt and pepper. Let it sit 10 minutes so the flavors marry. Taste and adjust acid and salt—chimichurri should be punchy.
Prep the steak. Pat the skirt steak dry with paper towels. Season both sides with salt, pepper, and smoked paprika. If the piece is very long, cut it into manageable sections.
Heat the pan. Use a cast-iron or heavy skillet over high heat. Add neutral oil and heat until shimmering and just starting to smoke. No timid sears here.
Sear the steak. Lay the steak flat and press for contact. Cook 2–3 minutes per side for medium-rare, depending on thickness. You're looking for a deep brown crust—aka flavor.
Rest and slice. Transfer steak to a board and rest 5 minutes. Slice thinly against the grain at a slight angle for tenderness.
Char the corn (optional but awesome). In the same hot pan, toss in the corn with a pinch of salt. Cook 2–3 minutes until lightly blistered. Deglaze with a squeeze of lime if you're feeling fancy.
Assemble the bowls. Divide hot rice into bowls. Top with sliced steak, charred corn, avocado, and pickled onions. Spoon chimichurri generously over the steak. Finish with lime wedges and fresh herbs.
Serve immediately. More chimichurri at the table. No one complains about extra sauce. Ever.
