Preheat the oven to 390°F (200°C). Grease or line a loaf pan (about 9x5 inches/23x13 cm) with parchment paper.

Cut the broccoli into florets and blend in a food processor until finely ground but not pureed. Transfer to a large mixing bowl.

Add the eggs, flour, baking powder, and salt. Stir until the mixture is smooth and evenly combined.

Pour the batter into the prepared pan and smooth the top with a spatula. Sprinkle with sunflower and sesame seeds.

Bake for 35 minutes, or until golden brown and a toothpick inserted in the center comes out clean. Allow the bread to cool in the pan for 10 minutes, then remove and cool completely on a wire rack before slicing.

Serve with sour cream or a slice of cheese for a light meal or snack.
