Pre-heat the oven to 400. Line a baking sheet with parchment paper and lightly mist the paper with cooking spray.
Lightly mist a large skillet with cooking spray and bring to medium heat. Add the spinach and cook for a couple minutes, stirring occasionally, until the spinach is wilted, Add the minced garlic and cook for an additional 30 seconds until garlic is fragrant.
Transfer the spinach and garlic to a mixing bowl and add the cream cheese, sour cream, Mozzarella, artichoke hearts, parmesan, pepper and red pepper flakes. Stir until well combined.
Fill a small dish with water and set it beside you on a clean, dry work surface (like a cutting mat). Lay a wonton wrapper on the mat. Scoop a tablespoon of the spinach artichoke mixture into the center of the wonton wrapper.
Dip your finger into the dish of water and run it along the entire outside edge of the wonton wrapper, corner to corner, creating a square of wet around the edge of the wrapper. Gather the four corners of the wrapper and bring them to the center, pressing them together. Use your fingers to press together all the edges of the wonton wrapper to seal the wonton bite closed. Place the finished bite onto the prepared baking sheet from step 1. Repeat with remaining ingredients to create 20 wonton bites. Mist the tops of the bites with cooking spray.
Place into the oven and bake for 10-12 minutes until the X at the top of the wonton bites are golden. Serve warm.
