1 large Vidalia or other sweet onion, thinly sliced vertically
¼ teaspoon kosher salt
1/8 teaspoon freshly ground black pepper
1 teaspoon garlic powder
1/2 teaspoon ground cumin
1/2 teaspoon dried oregano
1/4 teaspoon salt
1/4 teaspoon ground red pepper
1/4 teaspoon black pepper
4 rib steaks or prime rib (about 5 ounces each)
Heat a grill pan over medium-high heat until very hot. Brush pan with an oil-dampened paper towel or brush. Add onions; sprinkle with salt and pepper. Cook 8 minutes or until browned, stirring occasionally. Remove from pan; keep warm.
Combine garlic powder and next 5 ingredients (through 1/4 teaspoon black pepper) in a small bowl. Sprinkle garlic mixture over both sides of beef. Place steaks in pan. Grill 5 minutes on each side or until desired degree of doneness. Remove from pan and allow to rest 5 minutes. Top with onion mixture and serve.
