1. Peel and chop the garlic and onion, then sauté them in a pan over medium heat until they're soft and translucent.

2. Transfer the garlic and onion mixture to a large mixing bowl.

3. In the same pan, add 2-3 tablespoons (30-45 ml) of olive oil and cook 1 pound (450g) of ground meat until it's browned, breaking it up into small pieces as it cooks.

4. Add the cooked meat to the mixing bowl with the onion and garlic.

5. In the mixing bowl, combine the meat mixture with 1/2 cup (120g) of tomato puree, 1 tablespoon (15g) of chopped fresh basil, 1 teaspoon of paprika powder, salt, and pepper.

6. Mix well to combine.

7. In a separate bowl, combine 2 cups (250g) of mashed potatoes with a pinch of salt and pepper.

8. Set aside.

9. In a greased 9x13-inch (23x33cm) baking dish, create a layer of the potato mixture.

10. Top with the meat mixture, followed by another layer of potatoes.

11. Repeat this process until all the ingredients are used up, finishing with a layer of potatoes on top.

12. Sprinkle 1 cup (115g) of grated cheese over the top layer of potatoes and bake in a preheated oven at 225°C (425°F) for about 15 minutes, or until the cheese is melted and bubbly.

13. Serve the gratin hot, garnished with fresh basil leaves and a side of orange salad.

14. For the salad, simply combine peeled and segmented orange pieces with chopped fresh carrots (or other root vegetables of your choice).
