In a small bowl add in the garlic, herbs, olive oil and salt and pepper, mix well. Rub this mixture onto the steaks and set aside.
Preheat the BBQ to high. Grill the beef on medium high heat for 5 min. per side or until desired doneness. Depending on the thickness of the steak, it should be medium rare at this point. Remove the steaks to a plate to rest.
Meanwhile heat a medium sized cast iron pan over medium high heat. Add the tomatoes and stir and toss for 2 min. Add in the garlic and the pesto and continue cooking for 2-3 min. Add the basil and serve the pan on the board with the sliced steak for everyone to enjoy!
