¼ cup vegetable oil
1 medium onion, peeled and chopped
1 pound ground beef
Salt and freshly ground black pepper to taste
¾ cup chopped parsley or 4 teaspoons dried parsley
4 scallions, chopped
7 eggs, divided
1 medium potato, cooked and mashed
In a large skillet, heat oil over medium-high heat. Add onion; sauté 5 to 10 minutes, until golden brown. Add ground beef; sauté 5 minutes longer. Add ¾ cup water and salt and pepper to taste; reduce heat to low. Cover and simmer 10 minutes or until beef is tender. Remove from heat and let cool.
Preheat oven to 400 degrees. Grease 13- by 9-inch baking dish.
Dip matzas in water until wet but not soaked: Squeeze out excess water and break matzas into pieces. In large bowl, combine matzas, beef mixture, parsley, scallions, 6 eggs, and salt and pepper to taste; mix well and transfer to prepared baking dish.
In small bowl, blend mashed potato with remaining egg; spread evenly over meat mixture, if desired. Bake 45 minutes, or until golden brown.
