Instructions

1. 1Season the steak all over with salt and pepper, then slice into ¼-inch-thick strips.
2. 2Heat a large skillet over medium-high heat and add the sliced mushrooms to the dry pan. Cook 5 minutes, stirring occasionally, until golden brown and their moisture has released.
3. 3Push the mushrooms to the side, add olive oil, and increase heat to high. Once the oil is shimmering, add the onion and both bell peppers. Cook 3–5 minutes, stirring occasionally, until the vegetables begin to soften. Transfer to a plate.
4. 4Add the remaining olive oil to the skillet over high heat. Once shimmering, add the steak strips in a single layer (work in batches if needed). Cook 1–2 minutes per side over high heat until the exterior is deeply browned and caramelized. Transfer to the plate with the vegetables.
5. 5Reduce heat to medium, add the fresh garlic to the skillet, and cook 1 minute, stirring constantly, until fragrant. Return the steak and vegetables to the skillet along with any collected juices and stir to combine.
6. 6Turn on the broiler and position a rack in the center. Top the skillet contents evenly with part-skim mozzarella and grated parmesan. Place the skillet under the broiler and cook 2–3 minutes until the cheese is melted and bubbling.
7. 7Remove from the broiler and sprinkle with green onions. Divide the cheesesteak mixture evenly into 6 airtight containers while hot and refrigerate. Serve warm on toasted French or hoagie rolls.
