Wash and dry potatoes.
Dice to desired size. I tend to like mine more like those you'd buy frozen, so reasonably small.
Soak potatoes in water for the duration of your dicing session. You may choose to drain off and rinse the potatoes a couple times, until water doesn't get cloudy with stirring.
Drain water from diced raw potatoes. Drain as much possible, but no need to go through extra drying steps.
To the bowl of potatoes, add some chicken-like seasoning. Remember this is usually pretty salty, so use accordingly.
Add paprika for color and flavor. Smoked paprika could work here, too. This helps give a beautiful fried color, so be generous!
Add onion and garlic powder to bowl, for flavor. Add other herbs and spices, as desired.
Stir up ingredients of the bowl, coating each potato piece with some of each ingredient. If there doesn't seem to be enough coating, add some more!
Depending on the size of your air fryer, spread out in the bottom of air fryer. About 1-3 inches thick seemed to work for me, but make sure plenty of air can get around all of the potatoes, and don't try to cook too many at once.
Cook in air fryer, for about 13-16 minutes at 400°F. Depending on how heavily you load your air fryer, you may wish to give a good stir, or shake the potatoes around about every 5 minutes.
While cooking your potatoes, slice, dice, and mince the bell peppers, green onions, and other veggies, trying to stick with veggies that need about the same cooking time.
Remove pan from air fryer and add veggies, and stir around in with potatoes.
Air fry for another 3+ minutes to desired crispness.
Serve with plant-based sour cream, salsa or ketchup, and plant-based shredded cheese, or even sprinkle some fresh diced green onions on tap!
