Making homemade fajita seasoning is a lot easier than you might think, and you probably already have the ingredients in your spice cabinet. Simply combine a mixture of chili powder, cumin, paprika, cayenne pepper, garlic powder, salt, and black pepper, and voila, you're ready to make fajitas. Brighten up this dish with a mixture of red, orange, yellow, and green peppers. Top with your favorite garnishes. We use sour cream, pico de gallo, and guacamole.
