Jazz up plain popcorn with a little cumin and chili powder for an afternoon snack or for movie night.
Combine cumin, chili powder, salt to taste, cayenne and cinnamon in a small bowl.
Spread popped popcorn in an even layer in a large shallow baking pan. Lightly coat the popcorn with cooking spray. Sprinkle the spice mixture evenly over the popcorn; toss to coat.
