Gather all your ingredients. Slice the flank steak into thin strips, slice the onion and both bell peppers, and mince the garlic.
In a large skillet, heat the olive oil over medium-high heat. Add the sliced flank steak and cook for 3-4 minutes until browned. Remove from skillet and set aside.
In the same skillet, add the sliced onion and bell peppers. Sauté for 5-7 minutes until tender. Add minced garlic, salt, black pepper, and paprika. Cook for an additional minute.
Return the cooked steak to the skillet with the sautéed vegetables. Pour in the beef broth and stir to combine. Let simmer for 5 minutes.
Prepare your rice or cauliflower rice according to package instructions. Assemble your bowls by layering the cooked rice at the bottom, topping with the steak and vegetable mixture, and placing slices of provolone cheese on top. Cover for a few minutes to let the cheese melt.
Garnish with fresh parsley and serve.
