For the most tender bites, always slice flank steak thinly against the grain at a slight angle. If you prefer a milder chimichurri, reduce the red pepper flakes and add a splash more olive oil to soften the bite. Chimichurri develops even better flavor if made 30–60 minutes ahead; keep half for drizzling and avoid cross-contamination by not returning used marinade to the sauce. If grilling outdoors, preheat thoroughly to achieve a good sear without overcooking; for stovetop, use a cast-iron skillet and avoid overcrowding. Swap flank steak for skirt or flat iron with similar timings, adjusting by thickness, and consider adding grilled corn or roasted peppers to bulk up the salad.
