In a large skillet, heat the olive oil over medium high heat.
Add the onion and cook for 4-6 minutes, until softened.
Add the ground beef and seasonings (chili powder, paprika, dry mustard, cayenne, pepper, granulated onion, granulated garlic, oregano, sea salt, and cumin) and break into small crumbles, stirring to combine.
Cook the meat, stirring occasionally in the pan, until well-browned, about 6-8 minutes.
