This is most unusual.  I love the combination of cheese and tuna…this was a favorite of mine.  The cauliflower is not noticeable, however, it provides bulk and takes on the flavor of the tuna, so less tuna is required in the pie. The crust is very substantial and looks and tastes great!

MIRACLE DOUGH TIPS: - Please note:USE BOB'S RED MILL COCONUT FLOUR FOR ALL MY RECIPES AND ESPECIALLY FOR THIS MIRACLE DOUGH - COCONUT FLOURS DIFFER GREATLY IN THEIR ABILITY TO ABSORB MOISTURE!  There are several variations of this kind of dough on the internet, but mine is different to all the others out there.  I am getting very adept with this dough.  Use a fork to make it come together.  At first it looks impossible (might even have strings of cheese in it), but keep mixing and then turn out on a cutting board.  Knead for a couple of minutes, adding a bit of coconut flour as needed to make a lovely elastic dough. The more coconut flour one can add (usually about 1 tbsp or a bit more), the more bread-like the dough becomes (more substantial).  Since coconut flour is mostly fiber, you're not really adding much in the way of carbs, spread over several servings.  I put the dough ball on parchment paper and cover the dough with plastic wrap and using a  rolling pin (sometimes I use my special small one for pie dough), roll it out with ease.  If at any time the dough becomes resistant to rolling, nuke it about 10 seconds and away you go again!

2 tbsp bacon fat (30 mL)
2 cups finely-grated cauli-rice (500 mL)
Seasoning salt, to taste
Black pepper, to taste
1/3 cup water (75 mL)
3, 7-oz cans chunk light tuna, (199 g)
  in water
1/cup mayonnaise (125 mL)
1 cup grated Mozzarella cheese (250 mL)
4 oz regular cream cheese, softened (125 g)
3 tbsp chopped green onion, (45 mL)
  (green soft parts only)
1 egg yolk, fork beaten
Miracle Dough:  (Grain-free version below)
2 cups grated Mozzarella cheese (500 mL)
2 tbsp melted butter
1 cup Gluten-Free Bake Mix 2, (250 mL)
  (no gelatin needed)
1 egg, fork beaten
1/tsp onion salt (1 mL)
1/tsp garlic powder (1 mL)

Preheat Preheat oven to 350°F (180°C).

In frying pan, in bacon fat, stir fry cauli-rice for a few minutes. Sprinkle with seasoning salt and pepper, to taste.  Add water and cook until soft. 

In large bowl, combine tuna, mayonnaise, Mozzarella cheese, cream cheese and green onion.  Stir to combine.  Add cauli-rice and fold in.  Place mixture in 9-inch (23 cm) deep glass pie dish.  Pat down evenly.  Cover top with Miracle Dough. Press circumference of crust to pie plate to seal and pinch with your fingers for an attractive-looking pie. Cut a cross in the top of the pie to vent steam. Brush top of pie with egg yolk.  Bake 20 to 30 minutes, or until the crust edges are turning golden brown.  Serve with a salad.

Miracle Dough: In microwave oven in microwaveable bowl, melt Mozzarella cheese.  This took 2 minutes in my 1200 Watt microwave oven. Remove with oven gloves (be very careful!) or use a large measuring 4-cup (1 L) Pyrex dish with a handle.  Pour melted butter over top of molten cheese. Place Gluten-Free Bake Mix 2 on top. In small bowl, beat egg with fork.  Add onion salt and garlic powder; whisk with fork.  Add to Mozzarella cheese mixture. Stir with a fork to form a dough ball.  Knead for a short while and add a small amount more of the bake mix, if required to get a nice soft dough ball.  On a piece of parchment paper press dough out into a circle, cover with plastic wrap and roll out to fit top of pie dish.  

Helpful Hints:  For a Grain-Free version, use a bake mix made up of 2 cups (500 mL) almond flour and 2/3 cup (150 mL) coconut flour.  Use 3/4  cup (175 mL) of the mixture.  Or, simply use 2/3 cup (150 mL) almond flour and 2 tbsp (30 mL) coconut flour for each batch of Miracle Dough (I have not tested this smaller version, but the Grain-Free Bake mix - yes!). I still prefer the Miracle Dough goodies made with the Gluten-Free Bake Mix, however, this is an very lovely option and the net carbs get reduced by 1.0 gram per serving usually.
