Instructions
Make the tortilla bowls: Position a rack in the lower third of the oven; preheat to 450 degrees F. Put 4 empty cans (labels removed) or small ovenproof bowls upside down on a baking sheet.
Drape a square of foil over each can and coat with cooking spray.
Fill a shallow bowl with 1/2 inch warm water; whisk in the olive oil.
Soak each tortilla in the water until soft, about 5 seconds, then drape over the prepared cans, pleating as needed.
Bake until golden, about 5 minutes.
Remove from the oven and invert the tortilla bowls onto the baking sheet; remove the cans and foil.
Spray the inside of the tortilla bowls with cooking spray, season with salt and continue baking until crisp, 4 to 5 more minutes; let cool.
Meanwhile, make the steak: Whisk the dried garlic, onion and oregano, the cumin, chile powder, scallions, Worcestershire sauce, olive oil, 1 1/2 teaspoons salt and 1 teaspoon pepper in a bowl.
Put the steak in a shallow dish and rub with 2 tablespoons of the spice mixture (reserve the rest for the dressing).
Add the bell pepper and sliced onion and toss.
Cover and refrigerate 30 minutes or up to 4 hours.
Heat a large cast-iron skillet over high heat.
Add the steak and scatter the bell pepper and onion around it.
Sear the steak about 5 minutes per side, then transfer to a cutting board.
Continue cooking the pepper and onion until just tender, about 3 more minutes.
Thinly slice the steak against the grain, then cut into 1-inch pieces.
Assemble the salad: Whisk the mayonnaise, buttermilk and the reserved spice mixture in a large bowl until smooth.
Add the cucumber, lettuce, beans and olives and toss.
Divide the salad among the tortilla bowls.
Top with the steak, bell pepper, onion, cheese and salsa.
