Cajun Rub:
2 tablespoons olive oil
2 tablespoons brown sugar
1 tablespoon chili powder
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon seasoned salt
1/2 teaspoon paprika
1/2 teaspoon cayenne pepper
1/2 teaspoon kosher salt
1/2 teaspoon pepper
Mushrooms and Onions:
4 tablespoons salted butter
2 tablespoons olive oil
2 cups sliced onions
1 cup sliced mushrooms
2 tablespoons wine vinegar
1 teaspoon garlic powder
salt and pepper to taste
Trim fat from steaks and pat dry. Rub oil on both sides of steaks. In small bowl, combine remaining ingredients. Rub seasonings over oiled steaks on both sides. (You may store unused seasonings in covered container for later use.) Allow steaks to set out at room temperature for 30 minutes while you prepare your grill. Cook steaks on covered hot grill, until they reach desired doneness, about 8 minutes per side for medium-rare. Remove from grill and allow to rest uncovered for 5 minutes before serving.
For the side dish, heat butter and olive oil in medium skillet over low heat. Saute onion and mushrooms until tender. Add wine vinegar and season with garlic powder, salt and pepper. Serve steaks on a bed of onions.
