Preheat the oven to 350 F (180 C). Heat a 12” nonstick skillet over medium-high heat. I like to use a 12” blue steel pan. Melt in the lard once the pan is hot and swirl the pan. Add in the ground turkey and break up the meat with a spoon. Add in 1 teaspoon of sea salt and the Herbs de Provence.
Continue stirring and cooking the meat until it is fully cooked through. Pour the meat into a 9” x 13” casserole dish that has been sprayed with an avocado oil cooking spray or other oil.
In the same pan, add in the onions and mushrooms. Cook for 30 seconds, then add in ¼ tsp sea salt. Stir well. Add one tablespoon of water to deglaze the pan slightly and give the mushrooms some moisture.
Then add in cherry tomatoes that have been sliced in half and the baby spinach. Add in ½ teaspoon of balsamic vinegar. Stir well. Pour this mixture on top of the ground turkey in the casserole dish.
In a large mixing bowl, crack in the eggs and whisk them. Then add in 1 cup of water and whisk well to combine it. Add in ½ teaspoon of sea salt and whisk again.
Pour this mixture over the casserole. Bake for 30 minutes or until the casserole is puffed in the center and browned nicely on top. Cut into 9 squares.
