Bring a pot of water to a boil. Season with salt, add pasta and cook according to package directions. While pasta cooks, prepare steaks.
Season steaks lightly with a sprinkling of oregano, granulated garlic, and salt and pepper. Reserve any remaining seasonings for the sauce. Heat a medium-sized skillet. When it is hot, add the olive oil and the steaks. Sear steaks, without turning, approximately 5 minutes.
Turn steaks over, move to one side of skillet, and add mushrooms, onion, garlic, and reserved seasonings. Cook, stirring vegetables until softened, while steaks continue to cook, about 4 minutes. (These directions are for steaks cooked medium; shorten cooking time during searing for medium-rare.) Remove steaks and keep warm.
Add wine to deglaze pan. Cook about 1 minute and add marinara sauce. Heat through, about 4 minutes, to allow flavors to combine. Taste sauce and correct seasonings, if needed.
Drain pasta and toss with a 1/2 to 1 cup of cooking sauce. Serve with steaks, topped with remaining sauce. Mangia Bene!
