Remove the meat from the refrigerator and let it come up to room temperature. Preheat a broiler and bring a large pot of salted water to a boil.
In a small dish, combine the smoked paprika, marjoram or oregano, and grill seasoning. Rub the spice mixture evenly over the steak and transfer the meat to a broiler pan. Cook the meat under the broiler about 5-8 minutes on each side, to your desired doneness. Once cooked, remove steak from broiler, cover loosely with aluminum foil to keep warm and let rest.
While the steak is broiling, place a large skillet over medium-high heat with 2 turns of the pan of EVOO, about 2 tablespoons. Add the bell peppers, onion, garlic, salt and freshly ground black pepper, tent with foil, and cook until tender, 5-6 minutes.
