When the steaks are ready, transfer to plates or a clean cutting board and top with a few grinds of black pepper if desired. Add the green beans and 1 pint grape or cherry tomatoes to the pan and season with the remaining 1/2 teaspoon kosher salt. Cook over medium heat, stirring rarely, until the greens beans are crisp tender and the tomatoes are blistered in spots, 3 to 4 minutes. Add the garlic and cook until fragrant, about 30 seconds.
