Cheesy spinach bites✨

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