1Preheat broiler. Cut peppers in half, core and seed. Roast peppers, skin side up, until evenly blackened; put the peppers in a plastic bag, seal and let stand 15 minutes (allowing the steam to loosen the skins).
2Remove peppers and peel blackened skin. Dice peppers.
3In processor, combine mayonnaise, lemon juice, ginger, Worcestershire sauce, salt and pepper. Process 10 seconds to blend. Add roasted peppers, reserving 1/4 cup and process, pulsing on/off until peppers are coarsely chopped and sauce turns pink, about 6 seconds. Stir in reserved peppers and Tabasco; taste and adjust seasonings.
