  • 8 g Paprika
  • 8 g Onion Powder
  • 8 g Garlic Powder
  • 8 g Ground Cumin
  • 0.2 g Red Chilli Powder or Flakes
  • Salt To Taste

Chicken Fajitas

  • 1 kg Chicken Breast Sliced
  • 30 ml Avocado or Olive Oil
  • 1 Brown (Yellow) Onion Sliced
  • 2 Bell Peppers (Capsicum) Sliced
  • 5 g Oregano Fresh (Chopped) or Dried
  • Salt To Taste

Black Bean Coriander Rice

  • 200 g Long Grain Rice Washed
  • 400 ml Cold Water
  • 280 g Black Beans Rinsed
  • 10 g Coriander (Cilantro) Chopped
  • Salt To Taste

Guacamole

  • 1 Avocado Smashed
  • ¼ Red Onion Diced
  • 1 Tomato Diced
  • 5 g Coriander (Cilantro) Chopped
  • 1 Lime Juiced
  • 12.5 ml Avocado Oil
  • Salt To Taste

Wraps & Fillings

  • 7 Tortillas or Wraps Warmed
  • Salsa or Sauce of Choice

Method

  • In a bowl, mix the fajita spice mix and set aside. Reserve 1 Tbsp of the mix for the vegetables. In a second bowl, add the sliced chicken, salt and pepper, and the remaining fajita spice mix. Mix to combine.
  • In a bowl, combine the diced red onion, diced tomato, chopped coriander, and lime juice. Add the avocado and mash or mix through to your preferred texture, chunky or smooth. Season with salt and pepper and set aside.
  • Add the washed rice, cold water, and salt to a saucepan. Bring to a boil, reduce the heat to low, cover, and cook for 12 minutes. Turn off the heat and leave covered for 4–5 minutes. Remove the lid and fluff with a fork. Add the drained black beans and chopped coriander and mix to combine.
  • Place a large, high-rimmed pan or pot over medium-high heat. Add 1 Tbsp (20ml) of avocado oil and, once hot, add the onion and bell pepper. Sauté for 6–8 minutes, mixing regularly. Add the reserved 1 Tbsp of fajita spice mix and cook for 1 minute. Remove and set aside.
  • Place the same pan back over medium-high heat. Add the remaining 1 Tbsp (20ml) of avocado oil and sear the chicken for 4–5 minutes, or until golden and the internal temperature reaches 74°C (165°F). Add the oregano and the onion and bell pepper mix back to the pan and cook for 1 minute. Remove from the heat.
  • Slightly warm the tortillas and spread with the guacamole. Add the black bean and coriander rice, and top with the chicken fajita mix. Wrap tightly, tucking in the sides of the tortilla.
Chef's Tips
Butterfly the chicken breast evenly before slicing into strips — uneven thickness means thinner pieces overcook and dry out while thicker ones lag behind on the 4–5 minute sear.
Cook the spiced vegetables and chicken in separate passes, as written — doing them together steams the chicken in the vegetables' released moisture instead of letting it sear and brown.
Mash the avocado in last, straight before serving or portioning — mixing it through too early and letting it sit exposed to air is what causes the browning, even with the lime juice already in there.
Storage & Reheating
Refrigerate the chicken, rice, and vegetable mix for up to 4 days, or freeze the filling (without the guacamole) for up to 3 months, in an airtight container.
Keep the guacamole separate and add it fresh — unlike a tomato-based salsa, avocado oxidizes quickly even with lime juice mixed in, so it's best made fresh or eaten within 1–2 days, pressed with plastic wrap directly on the surface to limit browning if you do store it.
To reheat, warm the filling in a pan or microwave until hot throughout, then assemble the wrap fresh with the guacamole. If wrapping ahead for grab-and-go, wrap tightly in foil and reheat in the oven or a dry pan to keep the tortilla from going soggy.

Chicken Fajita Burrito Meal Prep Storage Instructions

Cool Down

Allow the cooked chicken fajita burritos to cool to room temperature (but do not leave them out for more than 2 hours).

Wrap Individually

To maintain freshness and prevent the burritos from drying out, wrap each burrito tightly in aluminium foil, plastic wrap, or parchment paper.

Store in an Airtight Container

Place the wrapped burritos in an airtight container or a resealable freezer-safe bag.

Refrigerate

Store in the refrigerator for up to 3-4 days.

Cool Completely

Let the burritos cool completely before wrapping.

Wrap for Freezing

Wrap each burrito tightly in aluminium foil, then place them in a freezer-safe bag. Removing as much air as possible helps prevent freezer burn.

Label and Freeze

Label the bag with the date and store it in the freezer for 2-3 months.
