These crispy cheesy bites are packed with spinach and flavor, perfect as an appetizer or snack! They're surprisingly easy to make and always a crowd-pleaser.
For extra flavor, consider adding a pinch of red pepper flakes for a little heat. You can also substitute other cheeses, such as cheddar or Gruyere, for some of the mozzarella or Parmesan. If you don't have fresh spinach, you can use frozen spinach, but be sure to thaw and squeeze out as much excess water as possible before adding it to the mixture.
