This is a family recipe (from my sister-in-law, Libby) that's a breakfast favorite! I've modified it to be gluten free.
1/2 cup butter (1 stick)
1/2 cup Pamela's Gluten Free Baking and Pancake Mix
1 lb cottage cheese
1 lb jack cheese, shredded
Popular additions/substitutions for the quiche: 1 lb diced cooked gluten free breakfast sausage or bratwurst, 4 oz can diced green chilis, bell peppers, onions or dried onion flakes, cheddar cheese or mixed cheddar/jack instead of jack cheese...use your imagination! BTW, I think that a whole stick of butter is a bit much, especially with all of the eggs and cheese in there, so I've used 1/2 a stick successfully.
Melt butter. Whip eggs until fluffy, add Pamela's baking mix, cottage cheese, butter, optional ingredients such as sausage, chilis, etc, and about 2/3 of the cheese. Put in 9" x 13" pan sprayed with non-stick spray. Top with remaining cheese. Bake 400 for 15 min, then lower temp to 350 and bake for 20-30 more min (until lightly browned on top). NOTE: be careful to verify that the cottage cheese, sausage, and non-stick spray are all gluten free!
