Add the cottage cheese, chili powder, cumin and paprika to a blender. Blend until completely smooth.
Pour the blended mixture into a microwave-safe bowl. Add the shredded Mexican cheese and microwave for 30 seconds.
Stir, then microwave for another 30 seconds, or until the cheese is melted. (If the queso is too thick, stir in a small amount of water or milk to reach desired consistency.)
Remove from the microwave and stir well. Mix in the diced green chiles.
Serve warm.
