Special equipment: wooden skewers
Soak wooden skewers in water for 30 minutes.
Place the scallops on paper towels to blot dry. Thread 2 skewers through 5 scallops. Repeat 2 more times. Sprinkle mint and rosemary over the scallops. Drizzle extra-virgin olive oil generously over the skewered scallops. Grind black pepper over the skewered scallops. Drizzle more olive oil over top and refrigerate for 30 minutes.
Season scallops with salt. Oil a hot grill and place the skewers over high heat for about 2 minutes on each side. At this point, you may brush on teriyaki or your favorite barbecue sauce. Serve immediately over pineapple salsa.
Oil your grill. Place pineapple slices onto hot grill for 4 minutes on each side. Gently toss the onion slices and jalapenos in olive oil. Place onto the hot grill for 3 to 4 minutes on each side. Remove from grill. Peel skin off of jalapenos. Cube the pineapple, removing the inner core. Cube the onion and mince the jalapenos. Combine all of them with the chopped herbs in a large bowl. Add lime juice and drizzle with olive oil. Season with salt and freshly ground black pepper, to taste.
