      Quiche Florentine

      • Preheat your oven to 350 °F (177 °C). Line an 8x8x2” baking dish or 9” pie plate with parchment paper. The paper can go up over the edge of the baking dish and you can trim it in a moment.
      • Prep and measure out all of the veggies and place them into a mixing bowl. Measure the spices into the bowl with the veggies and stir to combine.
      • Heat a skillet over medium heat for 2 minutes. Add the veggies & spices to the skillet and cook for about 6–8 minutes, until the veggies are soft and most of the liquid has evaporated. Set the bowl aside, you will use it again shortly.
      • While the veggies & spices are cooking, place the garbanzo bean flour, water, applesauce, nutritional yeast, tapioca flour, dijon mustard, and baking powder into the bowl and whisk until combined.
      • When the veggies are softened, transfer them to the mixing bowl and fold them into the mixture until combined.
      • Transfer the mixture to your baking dish and spread out evenly. Place the slices of tomato on top. Trim the parchment paper so it’s not hanging over the side of the baking dish. Bake for 35–40 minutes, until the filling is set in the middle, the top is golden brown and the sides have pulled away from the parchment paper.

      Nut-Free Cheesy Sauce

      • While your quiche is baking, make the sauce.
      • To your blender, add the oats, sunflower seeds, nutritional yeast, tapioca flour, onion powder, garlic powder, salt, mustard powder, white pepper, and nutmeg. Blend for about 20 seconds, until the ingredients come together into a fine powder.
      • Leave the powder in the blender and add the water, hemp seeds, non-dairy milk, miso, lemon juice, apple cider vinegar, tahini, and dijon mustard. Blend again until completely blended and smooth.
      • Transfer the mixture to a saucepan. Cook over medium heat, stirring often, for 10–12 minutes, or until the mixture thickens and achieves a thick, glossy, gooey cheese-like texture. Stir the sauce more consistently as it begins to thicken. If it doesn’t get thick at first, wait for it, it will. It may have lumps in the beginning, but it will smooth out as it thickens.


      • Slice the warm quiche and smother slices in the cheesy sauce. Garnish with fresh diced tomatoes if you'd like. Enjoy!


      • The quiche can be eaten the same day, but for best flavor refrigerate overnight to give the ingredients time to meld. Reheat in a 350 °F (177 °C) oven for about 10 minutes, until heated through.
