In a large bowl toss together tuna, bread crumbs, onions and pimiento. In a small bowl beat together egg and milk; stir in lemon peel. Stir in tuna mixture; toss until moistened. With lightly floured hands, shape mixture into eight 4-inch patties. In a large nonstick skillet melt butter. Fry patties, a few at a time, until golden brown on both sides, about 3 minutes per side. Place on an ovenproof platter in a 300? F oven until ready to serve. For sauce, in a small saucepan heat broth, lemon juice and dill. For each serving, spoon shredded carrots and zucchini onto each plate; top with 2 tuna cakes. Top each cake with a half-slice lemon; spoon sauce over.
