Heat the olive oil in a large skillet over medium heat. Add the sliced onion and green bell pepper, sautéing until they are tender (about 5-7 minutes). Add minced garlic and cook for an additional minute until fragrant.
Increase the heat to medium-high and push the onions and peppers to the side of the pan. Add the thinly sliced ribeye steak to the skillet, spreading it out in an even layer. Season with salt, pepper, soy sauce, and Worcestershire sauce (if using).
Cook the steak without stirring for about 2-3 minutes, allowing it to sear. Stir everything together, continuing to cook until the steak is cooked through and no longer pink (about another 3-4 minutes).
Reduce the heat to low and sprinkle the shredded provolone cheese over the steak mixture. Cover the skillet with a lid for a couple of minutes until the cheese melts.
To assemble the bowls, place a generous scoop of cooked rice at the bottom of each serving bowl. Top with the cheesy Philly cheesesteak mixture.
Garnish with fresh chopped parsley before serving.
Notes
For a healthier option, use brown rice instead of white rice.
