In a large skillet on medium heat, begin by adding enough olive oil to coat the bottom of the pan.
Place the steak in the pan and cook 3-5 minutes on both sides, or until well done. While it is cooking, sprinkle with garlic salt and rosemary (about 1 tsp). Place the steak on a paper towel lined plate to let the grease soak out.
In the same skillet add more oil if necessary then place the chopped sweet potatoes in the pan and drizzle a little more olive oil on top and rosemary. Let these cook for about 15 minutes, stir and mix to be sure they do not stick to the bottom of the pan.
Add in the green beans and add more olive or rosemary if necessary. Let this simmer for about another 10-15 minutes or until veggies are soft.
Once they are fully cooked, toss the steak back in and mix.
Serve with additional salt if necessary.
Note: The olive oil, garlic salt, and dried rosemary I added in by taste and amount that I preferred, you will need to use more or less depending on your preference.
