As a busy teacher, I think it's so nice to come home to a warm meal after a day in the classroom. I'm not the only one who thinks so: These beefy fajitas go fast at potlucks, too. —Mary Holmgren, Mackinaw, Illinois

  • 1 beef flank steak (2 pounds), halved crosswise
  • 1 medium green pepper, cut into strips
  • 1 medium sweet red pepper, cut into strips
  • 1 medium onion, halved and sliced
  • 1 envelope fajita seasoning mix
  • 1/2 cup beer or reduced-sodium beef broth
  • 8 flour tortillas (8 inches), warmed
  • 1 cup pico de gallo
  • Chopped fresh cilantro


  1. Place the first 5 ingredients in a 5-qt. slow cooker. Pour beer over top. Cook, covered, on low until meat is tender, 6-8 hours.
  2. Remove beef from slow cooker. Strain vegetable mixture; return vegetables to slow cooker. (Discard cooking juices or save for another use.) Shred beef with 2 forks; add to vegetables and heat through. Serve in tortillas with pico de gallo and cilantro.

Test Kitchen tips
  • Keep the pepper slices on the thick side. If cut too thin, they break down more during the long cook time.
  • We love adding fresh toppings to slow-cooked dishes. They add color, texture and bright flavor. That’s why we used pico de gallo instead of salsa.
