Preheat the oven to 350 ̊and place a 9” x 13” Pyrex baking dish in the oven to preheat for 10 minutes while making the fritada mixture.

Place the spinach in a large bowl and add the eggs, matzo meal or breadcrumbs, parmesan, salt and half of the olive oil. Mix well.

Carefully remove the preheated baking dish from the oven and add the remaining olive oil. Use a paper towel to rub the surface and edges of the pan with the oil. Place the fritada mixture into the pan and use a spatula to flatten the top of the fritada into one even layer. 

Bake uncovered for about 45 minutes, until the fritada is golden brown (the spinach will shrink quite a bit during cooking).

Serve warm with a dollop of sour cream or yogurt.
