In a large, deep skillet, heat the oil. Add the tomatoes, garlic and a pinch each of salt and pepper. Cook over moderate heat, stirring, until the tomatoes just start to blister, 4 minutes. Stir in the squid and cook over moderately low heat, stirring, until the squid turns opaque, 5 minutes. Stir in the vinegar and basil. Season with salt and pepper and serve.
