In a cast iron skillet on medium heat, add the ground beef and use a spatula or spoon to break it up into small pieces while it is cooking.  Then add the onions and cook until the ground beef is browned and the onions are tender. 

In a small bowl, mix together the red pepper flakes, black pepper, salt, oregano, onion powder, garlic powder, cumin, and chili powder.  Then sprinkle the seasoning mixture on the ground beef.

Stir in the diced tomatoes and chilies, tomato paste, Worcestershire sauce, brown sugar, and beer.  Turn the heat down to low and simmer for 30 to 40 minutes and it’s ready to serve.

This delicious beer hot dog chili is the perfect topping for hot dogs and bratwurst!
