Spicy Pork Chops (for 3 chops)

This is the ingredients for the rub

1/2 teaspoon garlic powder
1/2 teaspoon salt
1/2 teaspoon black pepper
1/2 teaspoon sugar
1/4 teaspoon thyme
1/4 teaspoon cumin
dash of red pepper (or up to 1/2 teaspoon if you want them spicy)

I would also like to add some moist ingredients that are saltly maybe soy and worstershire.

on the grill medium heat 10 minutes one side, flip and another 15-20 minutes on other side fully cooked but they are dry so i really think adding wet ingredients when cooking might be fun.
