  • 1 red bell pepper
  • 1 yellow bell pepper
  • 1 orange bell pepper
  • 1 White onion
  • 10 oz Steak - top round sirloin, or filet
  • 1 1-ounce packet of fajita seasoning
  • 1 tablespoon of olive oil
  • Limes and Cilantro for garnish


  • Slice peppers and onion into thin slices.
  • Cut the steak into 1/2 inch thick slices.
  • Toss the peppers with half of the fajita seasoning and olive oil.
  • Spread them out onto a sheet pan and cook at 400 degrees for 20 minutes.
  • Toss the steak slices with the remainder of the seasoning and oil.
  • Place the steak on top of the peppers and onions and cook together for 12 minutes at 400 degrees.
  • Switch the oven to broil to get char on the veggies and steak. Keep an eye on it because you do not want it to burn.
  • Squeeze a lime over the top and sprinkle on chopped cilantro.
  • Enjoy with tortillas, lettuce wraps or over a bed of lettuce along with your favorite toppings.


Tip on Cutting Steak: The best way to cut a raw steak is to freeze the steak for about 10-15 minutes so it's a little firm. You don't want it to be completely frozen but firm.
