Step 1

Season steak with salt and pepper. Drizzle with oil and Worcestershire, turning to evenly coat; let stand 10 minutes.

Step 2

Heat a large skillet (preferably cast iron) over medium-high. Add steak and cook, flipping once, until seared and medium-rare, 5 to 7 minutes total. Transfer to a plate. Return skillet to medium heat (do not wipe clean). Add 1 cup onion; season with salt and pepper. Cook, stirring occasionally, until translucent, 3 to 4 minutes. Add beans with liquid and 1/3 cup water; simmer until thickened slightly, 5 minutes. Smash with a potato masher or fork until spreadable. Thinly slice steak, then stir steak juices into bean mixture.

Step 3

Season tomato and avocado with salt. Spread bean mixture onto rolls. Top with steak, tomato, avocado, remaining 1/2 cup onion, crema, and hot sauce; serve.
