How to Make It
Heat a large nonstick skillet over medium-high. Sprinkle steaks evenly with Cajun seasoning and 1/4 teaspoon salt. Add steaks to pan; cook 5 minutes on each side for medium-rare or until desired degree of doneness. Place steaks on a cutting board; let stand 5 minutes. Cut across the grain into thin slices.
Combine remaining 1/4 teaspoon salt, tomatoes, and remaining ingredients in a bowl; toss well to combine. Spoon tomato mixture over steak.
