Preheat oven to 180°C and prepare a baking tray with baking paper. Set aside.
Cut each tortilla into 8 triangles and scatter on prepared tray. Drizzle oil on both sides and season with salt, pepper and paprika. Cook for 5-10 minutes or until golden. Remove from oven.
Sprinkle over grated cheese and cook for another 2-5 minutes or until cheese has melted. Remove from oven and set aside.
Dice tomato and add to a small bowl along with lime juice and season with salt and pepper to taste. Stir to combine.
Once tortilla chips have cooled slightly, place them on a serving plate and top with tomato salsa and sour cream. Garnish with basil leaves if desired and serve.
