Steam broccoli crowns in about 1 inch of water for 7 minutes until fork tender. Remove and cool slightly, then chop into tiny pieces.

In a large bowl, combine chopped broccoli, eggs, flour, mozzarella, feta, garlic, dill, onion powder, chili flakes, salt, and pepper. Mix until well incorporated and form into large balls.

Heat 2-3 Tbs olive oil in a large skillet over medium heat. Place the broccoli balls and flatten slightly. Cook for 6 minutes per side until golden brown. Adjust heat if necessary to prevent burning.
