Sweet potato lasagna with minced beef

Preheat the oven to 185 °C. Peel the sweet potatoes and cut or grate them into very thin slices, about 2-3 mm thick. Peel and crush or finely grate the garlic.

In a bowl, mix the cottage cheese with the egg, one teaspoon of oregano, salt, and pepper, then set aside.

In a deep pan, heat 2 tablespoons of olive oil and sauté the chopped onion (if using) and garlic for 1-2 minutes. Add the minced beef and brown it until it turns white, for about 10 minutes. Then stir in the thyme, rosemary, and chopped tomatoes. Bring to a boil, then remove from heat.
