Barbecue strip steak

Sauce

1. 1 In a pressure cooker, add the onion, garlic, and olive oil. Heat and sauté, stirring occasionally, for 2 minutes, or until the onion is translucent.
2. 2 Add the ketchup, lime juice, vinegar, sugar, Worcestershire sauce, mustard, salt, black pepper, and 1 cup of water. Close the pot and cook for 10 minutes.
3. 3 Remove from the heat, release the pressure, and open the pot.

1. 4 Meanwhile, rinse the meat, pat it dry with paper towels, and season with black pepper. Heat a cast-iron skillet until very hot, add the steaks, and grill for 10 minutes, or until done to your liking.
2. 5 Flip halfway through cooking, sprinkle with salt, and remove from the heat.
3. 6 Serve the strip steak with the sauce.
