I used eggplant bacon, broccoli, red pepper, red onion, and spinach for the veggies. I also did not follow the suggested crust recipe, but instead made a simpler one out of flour, butter, salt and water.
I had to cover the edges of the crust with foil after about 45 minutes of baking because it was getting too brown while the filling was still very under cooked.
The flavor was excellent! I added more veggies than the recipe called for so next time I will make a bit more of the filling, as there was plenty of room in the crust.
