Cook the steak:Heat 1 tablespoon of olive oil in a large skillet over high heat. Add 1½ pounds of thinly sliced sirloin steak. Cook, stirring occasionally, until browned on all sides, about 5 minutes. Remove the steak from the skillet and set aside.
Cook the onions and garlic:While the steak is cooking, slice your onion, mince garlic, and prepare the mushrooms, potatoes, and carrots.Add 1 more tablespoon of olive oil to the skillet along with the sliced onion. Season with 1 tsp kosher salt and ½ tsp black pepper. Cook over medium-high heat for 3–4 minutes, stirring frequently, until the onions begin to soften. Add 3 minced garlic cloves and cook for 1 minute.
Add mushrooms:Stir in 10 sliced cremini mushrooms and cook for another 3 minutes until the vegetables are tender.
Cook the potatoes and carrots:Pour ½ cup chicken broth into the skillet. Add 3 cubed red potatoes and 3 diced carrots. Bring to a boil, then reduce to a simmer. Cover with a lid and cook for 12–15 minutes, or until the vegetables are tender.
Make the sauce:In a small bowl, whisk together 2 tablespoons orange juice, 1 tablespoon lemon juice, 2 tablespoons soy sauce, ½ teaspoon dried oregano, ¼ teaspoon dried ginger, ½ teaspoon paprika, and ½ teaspoon chili powder.
Combine and finish cooking:Return the cooked steak to the skillet. Pour the sauce over everything and stir to combine. Cook for an additional 4–6 minutes, or until heated through.
Serve:Remove from heat and serve hot.
