Preheat your oven to 425°F (220°C) and spread the fries evenly on a baking sheet. Bake for about 15 minutes until golden and crispy, then remove and set aside.
Meanwhile, heat olive oil in a saucepan over medium heat. Add minced garlic and sauté until fragrant, about 30 seconds, then stir in the chili beans or chili sauce. Simmer for 5 minutes until the mixture thickens slightly and develops aromatics. Season with salt and pepper.
