Cheesy Spinach Bites

1. Preheat oven to 375°F and grease a 9x13 baking dish with butter or nonstick spray.
2. Sauté onions and garlic in butter (with salt and pepper to taste) until onions are translucent.
3. Cook spinach in microwave 3 minutes (or until thawed) and combine it in a large bowl with the onion mixture, flour, salt, baking powder, eggs, milk and parmesan.
4. Transfer the mixture into the baking dish and sprinkle with Parmesan on top.
5. Bake 30-35 minutes until a toothpick inserted in the center comes out clean.
6. Let cool slightly and then cut into triangles (or squares); remove from the baking dish with a spatula and place onto a baking sheet; bake for an additional 15 minutes and enjoy!
