Heat grill. Make Basil Tartar Sauce: Combine all ingredients in small bowl. Cover and refrigerate. Makes 1/2 cup. Process fish in food processor, pulsing just until shredded. Add onion, lemon juice, salt and pepper; pulse briefly to blend. Transfer to medium bowl; stir in egg white and bread crumbs. Shape into four 1/2-inch-thick patties. Brush both sides of patties with oil. Grill over medium-hot heat 4 to 5 minutes per side, until browned and cooked through. Meanwhile, grill tomato slices 3 to 4 minutes per side. Place burgers on bottoms of English muffins. Top each with 2 tablespoons tartar sauce, tomatoes and basil leaves. Top with muffins. Serve with potato chips, if desired. Makes 4 servings. A light, lemony burger served on a toasted English muffin with grilled tomato--tastes as great as a fresh crab cake at a fraction of the cost.
