Substitutions when making my vegan silken tofu quiche with onions and mushrooms:

This recipe contains gluten in my homemade vegan quiche crust recipe. You could try making it with buckwheat flour.

The filling of my vegan quiche is made with onions, mushrooms as well as silken tofu. The silken tofu filling can be replaced for a chickpea flour filling like in my spring asparagus chickpea flour quiche. Maybe if you have a soy allergy a chickpea flour filling will be best.

For the filling, I used caramelized onions and mushrooms but you could also use leeks, broccoli, zucchini or tomatoes.
