Cook quinoa if you haven't already. About 3/4 cup dried quinoa will yeild over 2 cups of cooked. Combine 3/4 cup quinoa with 2 cups water, bring to a boil, then reduce heat, cover, and simmer for 15 minutes, until fluffy and no liquid remains.
Grate the zucchini, measure 2 cups, and then put it in clean kitchen towel and squeeze all the water out of it into the sink.
Combine the chickpea flour and water in a small bowl to create a runny paste. This acts like an egg.
Saute onion and garlic over medium-high heat for about 10 minutes, adding small amounts of water as necessary to prevent sticking. Add the grated, squeezed zucchini and chopped spinach. Cook a few more minutes until liquid has cooked off and zucchini appears tender.
Remove from heat, and add the quinoa, chickpea flour mixture, almond flour, dill and salt and pepper. If your skillet is not big enough, you can transfer it all to a bowl. Mix well.
Heat a clean skillet or griddle to medium heat, about 350 degrees. Spray with cooking oil, if you'd like. Use a 1/3 cup measure to create equally-sized fritters, and form flat patties with your hands. Cook until golden brown on both sides.
You can crisp them further in the oven or air fryer for a few minutes, or just eat as is. My family loves them plain, but you could serve with dairy-free sour cream, hummus, or tahini dressing.
Notes
*Instead of almond flour, you can use a gluten-free flour blend, or probably any flour. The almond flour gives a delicious flavor, but it will still be yummy with a different kind. You can freeze individual raw patties and then later cook them in your air fryer for 10-15 minutes at 370 degrees. Or, freeze cooked ones, and later let them thaw and reheat on the stove.
