Heat oil in a skillet on medium high heat. Add the steak and sear until golden brown (about 5 to 7 minutes)
Add the fajita seasonings and stir well. Then add the bell peppers, red onion, and tomatoes. Saute until veggies are tender.
Drain the cooked pasta and add it to the skillet. Add the yogurt (or sour cream) and stir until thoroughly mixed.
Lastly, add the corn. Season with additional salt and pepper to preferred taste. Eat and enjoy!
