Preheat oven to 450 degrees, lightly oil baking sheet with 1 tablespoon of high heat oil. (Or use parchment paper and no oil.)
In a medium mixing bowl, combine chickpea flour with salt and spices and stir well. Add water slowly, only adding as much as you need to form a thick pancake batter, and whisk together until no lumps remain.
Add thinly sliced onion and chopped broccoli to the batter and stir to incorporate.
Spoon large dollops onto the baking sheet, spaced about 1-2' apart.
Bake for 7-8 minutes on each side, flipping when bottoms of fritters have turned brown and crisped up.
Serve with condiment of choice, alone, or over rice.
