Olive oil vs cooking spray

I'm making chicken kabobs tonight. Today is my first official day of solid foods...yay!!!

I was wondering if I can brush them with a little bit of olive oil before I put them on the grill or if I should spray them with cooking spray.

HELP!!!

Thanks

Yeah!!  Yum, kabob sounds good.  My hubby is Persian and makes really great kabobs.  You've got me planning a meal over here!! Either Olive Oil or Cooking spray is fine.  Either or, whichever your taste buds prefer.  In the future, if you are counting fat grams (and I DO NOT recommend you do at this point) - olive oil will have more fat the cooking spray, but it's the "GOOD" fat, not the BAD fat.   Enjoy!!  

For some reason I just found olive oil helped certain foods go down better, plus I love the stuff! Either should be fine
