Savory and creamy spanakopita filling, sandwiched between (or on top of for halves) flaky croissants.
Preheat oven to 350 degrees if using standard oven or toaster oven.
Add the butter to a medium saucepan on medium high heat.
Next add in the onion and cook for a couple minutes or until onion is translucent. Then follow with the garlic and cook for a few more seconds.
Add in the fresh spinach. Sauté until it is softened. Reduce heat and add in the seasoned salt and peppered egg, diced cream cheese pieces, mozzarella and feta cheeses; stirring continually until egg is cooked and cheeses are melted.
Remove from heat and spread spanakopita filling on one half of the split croissant and softened butter and/or other toppings (e.g. deli meats..) on the other half.
Place tops on croissant halves and place on a nonstick baking sheet.
Bake and toast sandwiches for 7 minutes until warmed through and croissants have crisped.
