Preheat the oven to 400°F (200°C).
Cook the sausage in a skillet over medium heat, breaking it apart as it browns. Add cumin and cayenne for extra flavor.
Mix in the cheeses by reducing the heat to low and stirring in the cream cheese and 1 cup of shredded cheddar or pepper jack cheese until smooth. Remove from heat.
Prepare the wonton cups by lightly spraying a mini muffin tin with cooking spray. Press a wonton wrapper into each cup, ensuring it forms a small bowl shape. Lightly spray the wrappers to help them crisp up.
Fill each wonton cup with the sausage and cheese mixture, then sprinkle the remaining shredded cheese on top.
Bake for 10 minutes or until the wontons are golden brown and crispy.
Let cool slightly, then garnish with chopped green onions or parsley if desired. Serve warm.
