For juicier results, keep the pan hot and avoid overcrowding so the steak sears instead of steams; medium-rare to medium (130–140°F) keeps flank steak tender, and thin slicing against the grain is essential. If using whole steak rather than pre-sliced, sear it 3–4 minutes per side, rest 5–10 minutes, then slice thinly. Adjust Cajun seasoning salt levels to taste, as blends vary, and add a squeeze of lemon or a drizzle of honey to balance heat. Warm tortillas prevent tearing; if meal-prepping, pack wet components separately and assemble just before eating.
