Make a sauce of sauteed diced onion, tomato paste, whole tomatoes, minced garlic, thyme, lime juice, salt, and pepper. Simmer 15 minutes. Put shredded lobster in sauce and mix thoroughly. Drizzle 1/4 cup cooking oil over mixture. Cover and let simmer. The lobster will absorb the oil and sauce and puff up almost like a souffle. Serve hot as main dish.
