I've made this twice for my family. I adapted it from a recipe given to me from a friend. The first time around I had to fudge around with the proper amounts for the "bread" portion (baking mix to water ratio), but I just made it again the other night with "proper" amounts of everything and it turned out fabulous!
1lb. ground beef
1 cup chopped onion
1/4 tsp salt
1 1/2 cups shredded cheddar cheese
1 cup G-F All Purpose Baking mix (I use Arrowhead Mills)
1/3 tsp. xanthan gum
1/4-1/2 cup milk (start with 1/4 and slowly add more as needed)
1. Preheat oven to 400-F
2. Brown beef and onions, drain. Stir in salt.
3. Scoop into a greased pie pan (I use a small amount of olive oil).
4. Sprinkle cheese on top of beef mixture.
5. Mix eggs, milk, and baking mix (combined with xanthan gum). Consistency should be similar to pancake batter (not too runny, but still able to "pour"). Add milk in small amounts until desired consistency.
6. Bake for 25 minutes, or until toothpick inserted in center comes out clean.
***We serve this with diced fresh tomatoes and organic leaf spinach over the top with a little G-F ketchup on the side for dipping.
