Preheat oven to 365°F.

Squeeze as much liquid as possible out of thawed spinach.

In a large bowl, add cream cheese and all three shredded cheeses, mix until combined. Add strained spinach, artichokes, and spices, and mix again until evenly combined.

Spray 36 mini muffin cups with cooking spray. Place one wonton wrapper in each cup, pressing gently to create a space in the center to hold the filling. Spray each wonton lightly with cooking spray.

Bake in preheated oven for 5 minutes to partially cook the wontons.

Scoop 1 tbsp of filling into the center of each wonton cup. Spray the edges of the wontons a final time to ensure they get extra crispy.

Bake again for 7 - 10 minutes until cheese is melted and wontons are crisp and golden brown.
