3 Tbs chili powder
1 tsp garlic powder
1 tsp onion powder
1/2 tsp crushed red pepper flakes (or to taste)
1 1/2 tsp sweet paprika
1 Tbs ground cumin
3 tsp kosher salt
3 tsp black pepper

Put all ingredients into a jar with a tight-fitting lid and shake.  This will last a few months in the pantry.

If using for tacos, start with 2 tbs per pound of meat and add to taste. When I use 1 lb meat and 1 can (rinsed and drained) black beans, I use 3 tbs of taco seasoning.
