01 - Preheat oven to 425°F. Toss fries with vegetable oil and salt until evenly coated. Arrange in a single layer on baking sheet. Bake 25-30 minutes, flipping halfway through, until golden brown and crispy.
02 - Heat olive oil in large skillet over medium heat. Add chopped onions and sauté 3 minutes until translucent. Add minced garlic and diced bell pepper, cook 2 additional minutes until fragrant.
03 - Add halal ground beef to skillet. Break up meat with wooden spoon while cooking 6-8 minutes until completely browned. Drain excess fat if needed.
04 - Sprinkle chili powder, cumin, smoked paprika, black pepper, salt, and cayenne pepper over beef mixture. Stir thoroughly to coat meat and vegetables evenly with spices.
05 - Add tomato paste, crushed tomatoes, and kidney beans. Mix well and bring to simmer. Cook uncovered 20-25 minutes, stirring occasionally, until sauce thickens to desired consistency. Adjust seasoning to taste.
06 - Transfer crispy fries to large ovenproof serving dish. Spoon hot chili evenly over fries. Sprinkle shredded cheddar and mozzarella cheeses across top.
07 - Return assembled dish to oven. Bake 5-8 minutes until cheese is fully melted and bubbling. Watch closely to prevent over-browning.
08 - Remove from oven. Scatter sliced spring onions and fresh herbs over top. Serve immediately while hot and crispy.
