Put 1 1/4 cups chickpea flour, 3 tablespoons nutritional yeast, and 1 1/4 tsp salt in a medium-sized mixing bowl and give it a stir.
Add 1 cup of water and stir well until it forms a smooth, thick paste.
Wash and shred zucchini into small pieces. (You can use a cheese grater or a food processor to chop it into small pieces.) Add 2 cups of firmly packed shredded zucchini to the bowl.
Dice a small onion and add it to the bowl along with 1/4 cup of bacon bits. Stir well with a silicone spatula to make sure everything is incorporated.
Add the mixture to a prepared 8 x 8-inch baking dish lined with parchment paper or well oiled if not using parchment.
Bake at 375° (190° C) for 40 minutes until the top is golden. Allow it to sit and cool for about 15 minutes before slicing. Serve either warm or cold.
Notes
Be sure to add 1 cup of the water and stir well until you have a thick paste with no lumps, before adding the remaining ingredients.
Let it cool for at least 15 minutes before cutting. It will firm up once it cools off a little.
