Zucchini Pie

This is a recipe my mom used to make in the summer to get rid of the zucchini that grew in our garden. I've adapted it, and it remains one of my favorite summer dishes.

Ingredients:
3 1/2 cups diced or grated zucchini
1 chopped onion
1 chopped red bell pepper
1 cup baking mix (e.g. Bisquick or other such mix. I use gluten-free bisquick or Bob's red mill gluten-free baking flour. if using a standard flour, add 1 1/2 teaspoons of baking powder)
3/4 cup extra firm silken tofu, blended
1 tablespoon ground flax seeds whisked with 3 tablespoons warm water
1/2 cup vegetable oil
1/2 cup vegan "cheese" (I use Daiya cheddar shreds)
1/4 teaspoon salt
1/8 teaspoon ground black pepper
1/8 teaspoon chipotle chili powder
1/8 teaspoon garlic powder
1 teaspoon Italian seasoning

Turn oven to 350 degrees (f). Mix tofu, flax seed mixture, oil, baking mix, and seasonings until smooth. Add remaining ingredients and stir until vegetables are evenly coated. pour into deep dish pie pan and cook for 30-40 minutes, until top is nicely browned and middle is cooked through.
