Using celery in your cooking adds crunch and colour. In this mix, the texture is a wonderful contrast to the tender peppers and onion. Look for different flavoured tortillas and different sizes to change up this dinner favourite
In a large nonstick skillet heat oil over medium high heat. Sauté celery, onion, red, orange and jalapeno peppers for 3 minutes. Stir in chili powder, cumin and half each of the salt and pepper; cook, for about 3 minutes or until vegetables are tender but still crisp. Remove to a bowl.
Sprinkle steak with remaining salt and pepper and oregano. Return skillet to medium high heat and brown steak well on both sides. Remove to a cutting board and thinly slice.
Return vegetables and beef to skillet and sauté to combine. Stir in cilantro.
Divide mixture among tortillas and squeeze with lime before enjoying.
