Combine the first six ingredients in a glass bowl.
Remove seeds from bell peppers. Cut peppers and onions into 1-inch cubes; toss with other ingredients in bowl. Cover and let marinate in the refrigerator 24 hours.
Before serving, thread the pieces of lobster, bell pepper and onion alternately onto skewers. Serve chilled immediately on a bed of crisp greens and garnish with a few sprigs of cilantro as a tasty appetizer. This also becomes an elegant main course when served over pasta or salad.
