Grilled flat iron steak with an earthy spice blend of garlic, onion, smoked paprika, and generous amounts of kosher salt and pepper. Served with delicious coleslaw.
In a small bowl, combine salt, pepper, onion powder, garlic powder, and smoked paprika. Evenly sprinkle the seasoning mix on both sides of the steak.
In a medium-sized bowl combine tomato paste, Worcestershire sauce, red wine vinegar, and water.
Add steak to a large re-sealable plastic bag. Add in tomato mixture and evenly coat with the marinade. Add olive oil to the bag and coat the steak.
Evenly sprinkle the onions and garlic over the steak, seal the bag, removing any air and refrigerate for at least 2 hours (1 day would be even better).
Remove the steak from the refrigerator and allow to sit at room temperature for 30 minutes. Lightly season steak with additional salt and pepper on each side.
Clean and oil grill grates. Preheat grill over medium-high heat. Transfer steak to the grill and cook to desired doneness, about 4 minutes per side for medium-rare. Remove steak from grill to a clean plate. Allow it to rest for 10 minutes before slicing. Slice against the grain and serve immediately.
