Sizzling Steak Fajitas

Heat 1 teaspoon of the oil in a large nonstick skillet over medium-high heat. Add the beef and cook, turning occasionally, until browned, about 6 minutes. Transfer to a plate.

Heat the remaining 1 teaspoon oil in the skillet over medium heat. Add the bell pepper, onion, and Southwest seasoning; cook, stirring occasionally, until the vegetables are very soft, about 8 minutes. Add the beef and cook, stirring occasionally, until heated through, about 1 minute.

Meanwhile, warm the tortillas according to package directions. Top each tortilla with about 1 cup of the beef mixture. Roll up and serve at once.
