Preheat oven to 425 degrees
Slice steak to your desired thickness and arrange in a pan for marinade. Combine Italian dressing, brown sugar, soy sauce, minced garlic and ground ginger. Combine thoroughly and pour over steak. Cover and set aside for 1-2 hours. If you have time and can make ahead, marinade overnight!
In a medium bowl add olive oil and assorted seasonings. Stir until combined. Add sweet potatoes and chopped onion and mix until evenly coated with mixture. Spread evenly over shallow baking pan and cook for 10-15 minutes.
Once sweet potatoes are done cooking at 425 degrees. Reduce the oven heat to 400 degrees. Move the sweet potato hash to one side of the baking pan. Place steak slices down the middle so they are not overlapping. Cook at 400 degrees for 5-8 minutes. **cooking depends on how thick your slices are and how well you like your steak. We like ours medium, so adjust the time cooked to your liking and remember, we still have green beans to cook too!
Combine green beans, melted butter and salt/pepper in a bowl and mix well. Once steak is done cooking, add green beans to the baking pan and cook for another 5-7 minutes. Then enjoy!
