In a small bowl, combine dry seasoning ingredients (cumin, garlic powder, smoked paprika).
Place all of the vegetables on a large baking sheet. Pour olive oil over the veggies and toss together to coat thoroughly.
In a cast iron skillet or heavy bottom pan, sear the steak to get a brown crust, about a minute on each side.
Remove the steak from the skillet and place in the middle of the vegetables on the baking sheet.
Sprinkle the seasoning mix over the top, turning steak and vegetables over to get all sides coated in seasoning.
Place the baking sheet in the oven and cook for 10-12 minutes, or until the internal temperature of the steak reaches 145 degrees F or your preferred doneness.
Remove from oven and let rest for at least three minutes. Slice beef to serve.
Sprinkle with salt and fresh parsley for a low carb meal!
