Whisk 2 eggs until the yolks and whites are mixed. Add 2 cups of sour cream, ½ teaspoon of salt, and ¼ teaspoon of pepper. Stir well. Add the cooked spinach and ⅓ cup of your favorite grated cheese.
Fill 12 muffin cups with the mixture. Top with grated cheese. Ask an adult to help bake on the middle shelf of the oven for 25 minutes.
Wait 5 minutes before removing the spinach treats from the muffin tray. Serve warm or at room temperature.
