Step 1

In a small bowl combine lime peel, lime juice, cilantro, jalapeno, sugar, salt, and pepper. Slowly whisk in oil until combined; set aside.

Step 2

In a large bowl combine scallops, pineapple, and avocado. Toss with 2 tablespoons of the lime juice mixture. Let stand for 15 minutes*, stirring occasionally.

Step 3

Alternately thread 4 scallops, 3 pineapple chunks and 2 avocado chunks on each of 4 12- to 16-inch skewers.

Step 4

Grill kabobs on a well-greased grill rack directly over medium-high heat for about 8 minutes or until scallops turn opaque, turning once halfway through grilling. Transfer kabobs to a serving platter and serve with remaining lime juice mixture. Makes 4 servings.
