This was written down somewhere in my mom’s handwriting. It was called Alsatian Dish. I think the name Quiche arrived more recently.
1⁄2 cup flour
1⁄4 teaspoon salt
1 lb. grated Monterey Jack cheese grated
1 lb. cottage cheese
1 teaspoon baking powder
1⁄2 cup cream

Beat eggs, add all but the onions.
Cover bottom of baking dish with sautéed onions. Pour other ingredients, mixed, over onions.
Bake in buttered shallow (2 ” deep, maximum) baking dish at 425 for 15 - 20 minutes, then drop heat to 350 for 15 - 20 minutes additional.
