Mix spices together to make a total of 2 tablespoon spice rub. Combine with ¼ c. water, ¼ c. olive oil, and ⅛ c. balsamic (or apple cider) vinegar. Place meat in marinade and soak for 1-2 hours. Grill.
For larger batches of spice rub, mix 2 parts (red pepper, black pepper, oregano, onion flakes, salt, and garlic salt) to 1 part (onion powder and chili powder).
