1. Blend eggs, matzo meal, parsley, salt and white pepper in large bowl. Shred potatoes, onions and zucchini in food processor. Place vegetables in colander and press out as much liquid as possible. Return vegetables in batches to food processor with steel blade and pulse until coarsely chopped. Add to egg mixture.
2. Heat electric griddle to 375 degree F. and oil lightly, or heat 1 tablespoon oil in large nonstick skillet over medium-high heat. Drop potato mixture by heaping tablespoonfuls onto griddle or skillet. Cook until golden, 5 minutes per side. Drain on paper towels; cover and keep warm. Repeat process with remaining potato mixture and additional oil as needed. Serve with applesauce, if desired. Makes 4 dozen.
