Ingredients

  • ¾ lb flank steak or sirloin
  • 2 medium red and yellow bell peppers
  • 1 medium yellow onion
  • 1 whole lime (juiced + zested)
  • 1 tsp cumin
  • ½ tsp chili powder
  • 8 count flour or corn tortillas
  • 1 set sour cream, salsa, cilantro (for serving)

Instructions

  1. 1

    Slice steak thin against the grain (about 1/4 inch). Cut peppers into 1/2-inch strips. Slice onion into thin half-moons.

  2. 2

    Heat oil in a large skillet over high heat until it shimmers, ~90 seconds.

  3. 3

    Add beef, season with salt, pepper, cumin, and chili powder. Sear 2–3 minutes, stirring occasionally, until browned. Transfer to a plate.

  4. 4

    Add peppers and onion to the same skillet. Cook 4–5 minutes over medium-high, stirring once halfway, until edges char and onion softens.

  5. 5

    Return beef to the skillet. Squeeze lime juice over the top, scatter zest, and toss for 30 seconds until combined.

  6. 6

    Warm tortillas in a dry skillet or over a flame 30 seconds per side. Serve fajitas with sour cream, salsa, and cilantro.
