Drain and dry shirataki noodles; dry-sauté 1–2 minutes and set aside. If using zoodles, spiralize and pat dry.
Heat 1 tbsp olive oil in a large skillet on high. Season steak lightly; sear in batches 45–60 seconds per side until browned but still tender. Remove and set aside.
Lower heat to medium and add remaining 1 tbsp oil. Sauté onion 3–4 minutes; add bell pepper and mushrooms and cook 4–5 minutes until softened. Add garlic and cook 30 seconds.
In a bowl whisk cream cheese with heavy cream until smooth (microwave 10–15 sec if needed). Stir in Worcestershire and 3/4 cup provolone. Pour into skillet and warm gently until smooth.
Return steak to skillet, add shirataki (or zoodles), and toss to coat. Cook 1–2 minutes to heat through.
Sprinkle reserved provolone and Parmesan on top, cover 1–2 minutes to melt or broil briefly for a bubbly finish.
Garnish with parsley/chives and serve with lime wedges.
