Pat steaks dry and season with salt and pepper. Sear in oil in a large skillet over high heat 2-3 minutes per side. Move to a plate.
Lower heat to medium. Cook sliced peppers and onion 5 minutes, then add garlic and oregano for 30 seconds.
Pour in crushed tomatoes and simmer 5 minutes until slightly thickened.
Nestle the steaks back in, top with mozzarella, cover, and simmer 4-5 minutes until the cheese melts and the steaks reach at least 145°F, then rest 3 minutes.
Serve with crusty bread to mop up the sauce.
