The smoky flavor from the grill enhances the natural sweetness of the vegetables, making each bite a delightful experience.
Most of the ingredients for this recipe are commonly found in your pantry or local supermarket.

Technique Tip for Perfect Fajitas
When grilling the vegetables, make sure to cut them into uniform slices to ensure even cooking. To enhance the flavor, you can marinate the bell peppers and red onion for at least 15 minutes before grilling. This allows the spices to penetrate the vegetables, resulting in a more robust taste. Additionally, avoid overcrowding the grill to achieve a nice char on the vegetables.

How to Store or Freeze Your Fajitas
Allow the grilled vegetables to cool completely before storing. This helps prevent condensation, which can make the vegetables soggy.
Transfer the cooled vegetables to an airtight container. If you have multiple layers of vegetables, place a piece of parchment paper between the layers to keep them from sticking together.
Store the container in the refrigerator. The grilled vegetables will stay fresh for up to 4 days.
To freeze, spread the cooled vegetables in a single layer on a baking sheet lined with parchment paper. Place the baking sheet in the freezer for about 1-2 hours, or until the vegetables are frozen solid.
Once frozen, transfer the vegetables to a freezer-safe bag or container. Label the container with the date to keep track of freshness.
When ready to use, thaw the vegetables in the refrigerator overnight. You can also reheat them directly from frozen by placing them in a skillet over medium heat until warmed through.
For the flour tortillas, store them in a resealable plastic bag or airtight container at room temperature for up to a week. If you need to store them longer, freeze the tortillas by placing a piece of parchment paper between each one and storing them in a freezer-safe bag.
To reheat the tortillas, wrap them in a damp paper towel and microwave for 20-30 seconds, or warm them in a skillet over medium heat for about 30 seconds on each side.
How to Reheat Leftovers
Stovetop Method:
- Heat a non-stick skillet over medium heat.
- Add a small amount of olive oil to the skillet.
- Place the leftover grilled vegetables in the skillet.
- Stir occasionally until the vegetables are heated through, about 5-7 minutes.
- Warm the flour tortillas in a separate skillet for about 30 seconds on each side.
Oven Method:
- Preheat your oven to 350°F (175°C).
- Spread the grilled vegetables evenly on a baking sheet.
- Cover the baking sheet with aluminum foil to prevent drying out.
- Heat in the oven for about 10-15 minutes, or until the vegetables are warmed through.
- Wrap the flour tortillas in aluminum foil and place them in the oven for the last 5 minutes to warm them up.
Microwave Method:
- Place the grilled vegetables in a microwave-safe dish.
- Cover the dish with a microwave-safe lid or plastic wrap, leaving a small vent for steam to escape.
- Microwave on high for 1-2 minutes, stirring halfway through.
- Check if the vegetables are heated through; if not, continue microwaving in 30-second intervals.
- Warm the flour tortillas by wrapping them in a damp paper towel and microwaving for about 30 seconds.
Air Fryer Method:
- Preheat your air fryer to 350°F (175°C).
- Place the grilled vegetables in the air fryer basket in a single layer.
- Heat for about 3-5 minutes, shaking the basket halfway through to ensure even heating.
- Warm the flour tortillas in the air fryer for about 1 minute, or until they are soft and pliable.
