Bring 1 inch of water to boil in a medium stick pot with a steamer basket.
Add broccoli florets, cover and steam for 4-5 min. Once it's fork tender (don't allow to overcook), remove from heat, then let cool.
Transfer broccoli florets onto a cutting board, and using a sharp knife, cut broccoli into very small pieces.
Add the chopped broccoli to a large bowl, together with the raw eggs, oat flour, garlic and green onions. Season with sea salt and pepper to taste and stir until well combined.
Heat about 1 Tablespoon of oil in a large non-stick pan over medium heat.
Take about a large-ish spoonful of your broccoli mixture (a slightly overflowing Tablespoon full), then flatten it between your palms and place it into the pan.
Repeat the process and cook about 4 fritters in each batch.
Drizzle the pan with a touch more of oil in between each batch.
Cook the fritters for 3-4 minutes, flipping them once in between.
Serve warm with plain Greek yogurt, no-sugar added ketchup, or homemade dip of choice such as our phenomenal Tzatziki sauce
