Taco Pie anyone?

My kids love Taco Pie, which is a recipe in Lisa Lewis' Special Diets for Special Kids Two. We call this pizza, because it looks like deep dish pizza. And, I've modified the recipe a little in a way that actually creates a "cheesy" texture to the inside. So, to get the original recipe, you'll have to buy the book. Here's my version:

Ingredients
------------
1 lb. ground beef
1/2 medium onion, chopped
taco seasoning mixture -- see recipe below
1 cup milk substitute (I use Darifree)
2 eggs (I use Ener-G egg substitute)
1/2 cup flour baking mix -- see recipe below
1/4 cup salsa (either homemade or I also will use Tostitos brand milk salsa. Frito Lay claims this is GF, CF, MSG free, soy free and egg free. See the company's allergen info here.)

So, first, cook the beef over a medium heat with the onion.

While it's cooking, make the taco seasoning. This is 2 tsp onion powder, 1 tsp chili powder, 1/2 tsp crushed dried red pepper, 1/4 tsp oregano, 1 tsp sea salt, 1/2 tsp tapioca starch, 1/2 tsp garlic powder, 1/2 tsp cumin. Mix well.

Heat oven to 400.

Now, make the flour baking mix. This is my version.
- 2.75 cups gf flour (3/4 cup sorghum flour, 1 cup tapioca starch, 1 cup potato starch)
- 1/8 cup baking powder
- 2 tsp xanthan gum
- 1/2 tsp cream of tartar
- 1/2 tsp sea salt
- 2-3 tbsp sugar
- 1/4 cup canola oil
Mix the dry ingredients well in a bowl. Pour in oil. Then mix well with a beater to blend oil in.

Grease a pie plate. I use Spectrum organic shortening.

Drain meat mixture. Pour into pie plate and spread around.

Top with salsa, as much or little as you want. I do it in blotches. If I don't have salsa, I pour a little ketchup here and there.

If you're using egg subs, make them first and let sit a few minutes.

In a bowl, combine milk sub, egg (or egg sub), and baking mix until blended. It may be a little lumpy and that's OK. It will be liquidy. Pour over the meat mixture.

Bake for 30-35 minutes or until toothpick comes out cleanly.

Easy variations of this are hamburger pie, by eliminating salsa and taco seasoning. You could add an onion seasoning mix to this if you wanted.
