Toss all the sliced peppers and onions in a large bowl with the olive oil and salt until well coated. Place in the basket of the air fryer.
Cook for 7-9 minutes, shaking the basket halfway through, until vegetables are starting to turn tender, and brown around the edges. I like a little crunch to be left in the vegetables.
Enjoy! I love using these on fajitas, or taco bowls.

Notes
To make this on the stove top: Heat the olive oil in a deep skillet, then add the sliced veggies and sprinkle with salt. Cook, stirring frequently, 8-10 minutes or until done.To oven bake: Spread the veggies out in a single layer on a baking sheet, and cook for 20-25 minutes at 400 F (200C) until done.You can double the recipe, but you'll need to cook them in two batches in the air fryer.Storing leftovers: Leftovers will last 4-5 days tightly covered in the fridge, and freeze for 4-6 months
