Step 1

Preheat oven to 350 degrees F. Sprinkle meat with steak seasoning. In a 12-inch cast-iron skillet heat oil over medium-high. Add meat and broccoli rabe. Cook 4 minutes, turning broccoli rabe once (do not turn meat). Place peas around meat. Transfer skillet to oven and bake 8 minutes or until meat is medium-rare (145 degrees F). Remove meat and vegetables from skillet; cover and keep warm.

Step 2

For sauce, add mushrooms to drippings in skillet. Cook over medium-high 3 minutes, stirring occasionally. Whisk together the beef broth, mustard, cornstarch and salt; stir into mushrooms. Cook and stir until thick and bubbly. Cook and stir 1 minute more. Serve meat and vegetables with sauce.
