For vegetable waffles, wash zucchini, peel carrots and coarsely grate both. Roast sesame seeds in a non-stick pan without fat. Mix flour with baking powder. Beat margarine, eggs and salt with hand mixer until fluffy. Add vegetables and sesame seeds to egg-fat mixture and mix.
Stir in flour and mineral water alternately by tablespoonfuls. Heat waffle iron, grease and spread 3 tablespoons of batter per waffle on the waffle iron and bake 8 waffles in succession.
