In a pan over medium-high heat, brown the beef and season with salt and pepper.

Cook until no longer pink, about 5 minutes.

Drain any excess drippings, but keep the beef in the pan.

Add the Italian seasoning, chili powder, cumin, salt and pepper to the beef and stir to combine.

In a small bowl combine the mayonnaise and Dijon mustard.

Divide the lettuce, tomatoes and onion between the 3 bowls and top with cooked beef and the Dijon mayo. Enjoy!
