In a medium mixing bowl, whisk together eggs, melted butter, flour, tomatoes, spinach, cottage cheese, mozzarella cheese, and salt until well combined. Pour into prepared pan.
Bake for 15 minutes. Then reduce oven temperature to 350 degrees F and bake for another 30-35 minutes.
Remove from oven and cool for 5-minutes. Cut into 12 slices and serve warm. Top with additional toppings if desired.
