Layered Lemon-Tomato Aspic

Heat tomato sauce in a small saucepan over medium-low heat, about 3 minutes. Stir in lemon-flavored gelatin until dissolved. Remove from heat and stir in cold water and vinegar.

Mix cottage cheese, celery, green bell pepper, green onions, parsley, mayonnaise, horseradish, salt, pepper, Worcestershire sauce, and hot sauce in a large bowl. Cover and place in the refrigerator.

Pour 1/2 the tomato mixture into an 8-inch square baking dish. Refrigerate until firm, about 1 hour.

Spread cottage cheese mixture over the tomato mixture. Refrigerate for 1 hour.

Spread remaining tomato mixture over the top and chill until set, about 1 hour more.
