Make It Now:

1. Make the Marinade: Open 2 gallon-sized freezer bags. To each one, add the following:

  • 2 tablespoons oil 
  • Zest of 1 lime (about 1 1/2 teaspoons)
  • 3/4 teaspoon cumin
  • 3/4 teaspoon chili powder
  • 1/2 teaspoon oregano, crushed in hand
  • 1/2 teaspoon salt
  • 1/4 teaspoon pepper
  • 1/4 teaspoon garlic powder
  • Small pinch of red pepper flakes

Use your hands to massage the bags from the bottom and combine the marinade. Then, add the steak to one bag and the chicken to the other (DO NOT ADD THEM TO THE SAME BAG), seal, and toss until the meat is evenly coated. (Freezing instructions begin here.) 

2. Marinate the Chicken and Steak: Place the steak and chicken bags in the refrigerator to marinate for at least 1 hour and up to 24 hours, turning and/or massaging occasionally.

3. Stir Fry the Veggies: In a large skillet, heat 2 tablespoons oil over medium high heat until shimmery. Carefully add the peppers and onions to the hot pan and saute until softened and charred, 5-7 minutes for fresh veggies or 7-9 minutes for frozen veggies. Season lightly with salt and pepper and the sugar (a key ingredient!) as they cook. Remove to a platter.

4. Stir Fry the Chicken and Steak: Add 1 tablespoon of oil to the pan. Once it’s shimmery, saute the steak in one batch until brown on all sides, about 3 minutes. Then, saute the chicken in second batch, about 4-5 minutes (make sure there’s no more pink on any of the chicken!). Remove to the serving platter with the veggies.

5. Serve: Squeeze half a lime over all the meat and veggies. Top with chopped cilantro, if desired. Warm the tortillas according to package directions. Serve the meat and veggies on the tortillas with lime wedges and your favorite Tex-Mex toppings.

Freeze For Later:

Follow Step 1. Freeze the marinated steak and chicken bags, alongside frozen peppers and onions. Two options for the frozen peppers and onions: 1) Buy a 20-22 ounce bag of frozen sliced peppers and onions, or 2) line up the fresh onion and pepper slices in a single layer on a sheet pan. Place in the freezer until solid and then put frozen veggies in a freezer bag.

Prepare From Frozen:

Thaw the bags of steak and chicken using one of these safe methods, but do NOT thaw the peppers and onions. Follow Steps 3-5.


*Don’t hesitate to ask your butcher to slice the meat for the fajitas to save you time!

**Shortcut: Replace with 20-22 ounces of frozen pepper and onion blend from the freezer section.

What’s the Heat Level of This Recipe? Overall this recipe isn’t very spicy at all, so all ages can enjoy these. If you’d like more heat, simply add in more red pepper flakes to the marinade.
