For the marinade and steak: Combine the cilantro, Worcestershire, garlic, chiles, lime juice, marjoram and onions in a bag. Sprinkle the steak with salt and pepper and add to the bag. Release air and seal the bag, then refrigerate. Marinate up to 2 hours.
To prepare, bring the steak to room temp, heat a grill pan to medium-high, shake off excess marinade and cook the steak for a few minutes on each side. Thinly slice and set aside.
For the soup: Bring a pot of water to a boil, salt the water and cook the barley to tender, but al dente, about 20 minutes. Drain and drizzle with a touch of oil. Store in a plastic container until the night you serve the soup.
In a soup pot, heat the 2 tablespoons EVOO, 2 turns of the pan, over medium-high heat. Add the garlic, celery, chile peppers, onions and bell peppers, and season with salt and pepper. Cook to soften the veggies, 8 to 10 minutes. Add the stock, tomatoes and cilantro, and simmer to combine the flavors, about 20 minutes. Cool, cover and store for a make-ahead meal.
To serve, heat the soup to a low boil. Add the barley and heat through. Serve the soup in shallow bowls and add the sliced skirt steak. Pass the lime wedges, Worcestershire and hot sauce for topping.
