Sauté the minced meat in a drizzle of olive oil with the finely chopped onion; then season with salt and pepper
Clean the spinach leaves, and put them in a saucepan with about 1 tbsp of oil, just enough time to wilt the leaves.
Mix the meat with the raw eggs, keeping a yolk aside for decoration later.
Line the bottom and the sides of a baking tray tin with half the puff pastry.
Place half of the meat mixture; then wrap each hard-boiled egg into spinach leaves and arrange them in a row in the middle of the mold
Pour the second half of the meat mixture; then cover with the rest of the puff pastry and make diamonds with strips of dough.
Beat the egg yolk. Brush the dough with a brush. Top with the fennel seeds.
Preheat the oven to about 390° F; bake for about 45 minutes
