Process until it is a thick puree.
Slowly pour in the rest of the olive oil while the processor is running.
Season with salt and pepper and transfer to a bowl.
Using metal skewers, thread and folded a zucchini slice followed by a piece of scallop threaded through the middle so the round side of the scallop is facing out. Repeat until the skewer is full ending with a folded zucchini.
Season the skewers with salt and pepper and brush all over with enough parsley sauce to cover. Refrigerate for 30 minutes.
Save left over parsley sauce for another day. It will stay 4 days in the refrigerator
Preheat your grill so it is nice and hot. Oil the grill.
Grill the skewers until lightly brown, about 3 minutes. Turn once using tongs. If they are sticking let them cook a little more.
Grill on the other side of the scallop until just cooked through about 3-4 more minutes.
Meanwhile grill the lemon wedges until slightly charred.
