This is an easy chili powder, which tastes pretty similar to the pre-mixed stuff.
- 1 Tbsp ground cumin
- 2 tsp garlic powder
- 1 tsp cayenne pepper
- 1 tsp paprika
- 1 tsp ground oregano

Note that although store bought chili powders usually contain salt, this mix has none. So when substituting this powder into your recipes, you may need to add more salt yourself.
