Herb-Marinated Tilapia Kebabs

Tilapia always seems to be on sale so I bought some.  Usually I'm nervous about putting fish directly on the grill (because it always sticks - for me at least) but I was willing to give it a shot.  This recipe I found in Rachel Ray's Everyday magazine incorporates tilapia & set my fears aside for grill-sticking fish.  It makes for a great light dinner. I served mine with a side of baby arugula & black wild rice.

PS: It's July - when did that happen?
