Saut Vegetables: Heat 2 tablespoons of olive oil in a skillet and add 8 ounces of sliced baby Bella mushrooms. Cook until soft, about 5 minutes. Then, stir in 2 cups of fresh baby spinach, cooking until wilted. Remove from heat and let cool.
Make the Cheese Filling: In a mixing bowl, combine 15 ounces of whole milk ricotta cheese with 2 large eggs and the remaining Parmesan cheese. Add salt, pepper, and the cooled spinach and mushroom mixture, blending until well combined.
