Cut the chicken into thin strips, either lengthways or crossways. If you are using mini fillets, slice them in half horizontally (parallel to the board) so they are thinner.*You can also cut it into cubes.
Mix the spices and toss the chicken in them. Season with salt and pepper, and toss everything in the oil.
Thread the chicken onto the skewers, folding the strips back and forth so they sit in layers. Push the pieces together so they sit snugly, but do not squash them.
Cook the skewers in the air fryer for about 10-12 minutes at 200°C, or in the oven for about 10-12 minutes at 215°C.*The time may vary depending on which air fryer or oven you use, and on the thickness of the pieces — so check on them as they cook.
Mix the ingredients for the mayo and brush it onto the hot skewers.
