Preheat oven to 425° F. Heat a large skillet over medium-high heat. Add beef, onion powder, chili powder and cumin. Cook until beef is cooked through, about 4 minutes. Add salt and pepper to taste.
Generously coat a baking sheet with oil or cooking spray. Spread out tortillas on a work surface and evenly distribute each with beef mixture and cheese. Roll tight into a cigar shape. Place seam side down on baking sheet. Coat each roll with oil or cooking spray and cook until crisp, about 15 minutes.
Meanwhile, combine dressing and salsa in a small bowl. Season with salt and pepper to taste. Serve with beef rolls.
