Preheat your oven: Set your oven to 375°F (190°C) and lightly spray a 10½ x 7½” baking dish with olive oil to prevent the bars from sticking.
Prepare the broccoli: Boil water in a pot, then add the 7 oz of broccoli florets and 1 tsp of salt. Blanch the broccoli for about 1 minute, then chop it roughly and set it aside.
Sauté the scallions: In a skillet, heat 1 tsp of olive oil over medium heat. Add the 4 diced scallions and sauté for about 1 minute until soft. Remove from heat and set aside.
Mix the dry ingredients: In a large mixing bowl, combine 1¼ cup of flour, 1 tsp of baking powder, and 1 tsp of salt. Stir the mixture well to ensure an even distribution of the leavening agent.
Add wet ingredients: Add 1 cup of milk, 2 lightly beaten eggs, and ¼ cup of olive oil to the dry ingredients. Stir until the mixture thickens and forms a batter.
Incorporate the fillings: Gently fold in the crumbled 4 oz of feta cheese, 4 oz of mozzarella cheese, the chopped broccoli, sautéed scallions, and 3 tbsp of fresh dill into the batter. Make sure everything is evenly combined.
Prepare for baking: Transfer the mixture into the prepared baking dish, spreading it evenly. Sprinkle 3 tbsp of grated pecorino cheese on top and feel free to lightly spray it again with olive oil for extra browning.
Bake: Place the dish in the preheated oven and bake for 45-50 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
Cooling: After baking, let the bars cool in the pan for about 10 minutes before slicing them into squares or rectangles. Serve warm or at room temperature!
