Spray a 13 x 9-inch baking sheet with a keto-friendly cooking spray and set aside. Turn on your broiler and move an oven shelf to the highest position in the oven.
While your oven heats, place the flank steak into a large bowl. Add in the flank steak, 2 tablespoons of oil, lemon juice, and the Spicy Meat rub. Mix well with your hands, turning the flank steak to coat it in the marinade. Set aside and let this marinate while you chop the vegetables.
Place chopped vegetables on the prepared sheet pan. Pour 1 tablespoon of oil over the vegetables. Add 1 teaspoon of salt. Use your hands to mix the vegetables with the oil, squishing lightly to macerate the vegetables. Move the vegetables onto one side of the sheet pan, spreading them in one thin layer.
Broil for 6-8 minutes. Check the flank steak with a meat thermometer (135F for medium rare). If the steak is ready, use a set of tongs to remove it to a plate. Cover the plate and allow the steak to rest for 10 minutes.
