Cook the fries: Bake or fry your French fries until golden and crispy. Set aside.
Sauté the vegetables: In a skillet, heat olive oil over medium heat. Add sliced bell peppers and cook for about 4–5 minutes until slightly softened.
Cook the steak: Add the thinly sliced steak to the skillet with peppers. Season with garlic salt and black pepper. Cook until browned and cooked through.
Assemble: On a plate, arrange the fries. Top them with the cooked steak and peppers.
Add cheese: Sprinkle shredded cheese generously over the top.
Melt the cheese: Place the plate in the oven or microwave just until the cheese melts.
Serve hot: Garnish with black pepper or fresh herbs if desired.
