Marinate or season the steak: Pat the steak dry. Rub with olive oil, salt, pepper, and smoked paprika.
Let it rest at room temperature for 20–30 minutes for even cooking.
Make the dressing: In a small jar, whisk or shake together olive oil, lemon juice, Dijon, garlic, oregano, honey, salt, and pepper. Taste and adjust—add a pinch more salt or lemon if needed.
Prep the salad base: In a large bowl, combine greens, tomatoes, cucumber, red onion, olives, and herbs. Don’t add the feta, nuts, or avocado yet.
Cook the steak: Heat a cast-iron skillet or grill over high heat until very hot.
Cook 3–5 minutes per side for flank or skirt (thickness matters). Aim for medium-rare to medium. Use a thermometer if you have one: 130–135°F (54–57°C) for medium-rare.
Rest the steak: Transfer to a plate and let it rest 5–10 minutes.
This keeps the juices in the meat and off your cutting board.
Toss the greens: Drizzle about half the dressing over the salad base and toss gently until lightly coated.
Slice the steak: Slice thinly against the grain. If using flank or skirt, angle the knife slightly for wider, tender slices.
Assemble: Arrange the dressed greens on a platter. Top with sliced steak, feta, avocado, and nuts or crushed pita chips.
Spoon on more dressing to taste. Finish with a few extra herb leaves and a crack of pepper.
Serve: Serve immediately while the steak is warm and the greens are crisp. Pass any remaining dressing at the table.
