Instructions
Grease a casserole dish. (The one I use is about 8x12-inches.)Preheat oven to 350 degrees.
Place squash and onion in a large pot. Add water just to cover. Add 1 teaspoon of salt. Bring to a boil. Reduce heat to medium-low and simmer until squash is soft, about 7 minutes. Drain well.
In a large bowl, mix together mayonnaise, sour cream, egg, black pepper, and remaining 3/4 teaspoon salt.
Stir pimentos, squash and onion, and 1/2 the cheddar cheese into mayonnaise mixture and transfer to prepared casserole dish.
Sprinkle remaining cheddar cheese and the crushed crackers on top. Bake for about 25 minutes.
