Chop up the chicken breasts into chunks about an inch wide.

Grab 8 wooden (soaked) or metal skewers and load the chicken pieces onto each one.
03 -
Toss the grated Parmesan, vinegar, olive oil, lemon juice, garlic powder, oregano, onion powder, red pepper flakes, salt, and some pepper into a bowl. Whisk together until it all comes together nicely.

Slather the marinade all over your skewered chicken. Pop it in the fridge, covered, for at least half an hour or let it sit up to 12 hours if you've got time for bigger flavor.
05 -
Get your grill hot over medium. Cook the skewers with the lid down, turning every five minutes or so, until they're browned all around and the chicken hits 165°F inside.

Move the cooked skewers onto a big plate and enjoy while they're hot.
