Prepare the Zucchini Rolls: Preheat your oven to 400°F (200°C). Cut the zucchinis in half lengthwise and scoop out the insides with a spoon to create hollow 'rolls.' Place them in a baking dish, drizzle with olive oil, and sprinkle with salt. Bake for 10-15 minutes to soften slightly.
Cook the Steak: In a large skillet over medium-high heat, add 1 tablespoon of olive oil. Once hot, add the thinly sliced ribeye steak. Season with garlic powder, black pepper, and salt. Cook for about 3-4 minutes until browned but still tender. Remove the steak from the skillet and set aside.
Sauté the Vegetables: In the same skillet, add the remaining tablespoon of olive oil. Add the sliced onion and bell pepper and sauté until they become soft and caramelized, about 5-7 minutes. Return the cooked steak to the skillet, mixing it with the veggies.
Fill the Zucchini Roll: Take the baked zucchini halves and spoon the steak and vegetable mixture into each one, filling them generously. Top each filled zucchini with a mix of provolone and mozzarella cheese.
Bake the Rolls: Reduce the oven temperature to 375°F (190°C). Place the zucchini rolls back into the oven and bake for an additional 10-12 minutes until the cheese is bubbly and golden.
Serve: Remove from the oven and let cool for a few minutes. Garnish with chopped fresh parsley if desired before serving.
Notes
Arrange the zucchini rolls on a platter and drizzle with a little olive oil. You can place fresh parsley leaves between the rolls for a pop of color.
