Dynamic LINQ function using dictionary as a Parameter to filter method

I am new to the reflection area. I am have to filter a list of entity that has a dictionary by using it's key and value like below

public class Person
{
    public string Name { get; set; }
    public Dictionary<string,string> SecQuestions { get; set; }
}

below extension is available in a dll and could not be modified

public static class extensions
{
    public static List<Person> FilterMe(this List<Person> Persons, Func<Person,bool> predicate)
    {
        // Logic to filter the persion list
        return Persons;
    }
}

hence I have to call the above method by using below code

persons.FilterMe(xy => xy.SecQuestions.Any(x => x.Key == "PlaceOfBirth" && x.Value == "Madurai"));

I need to know how to create

xy => xy.SecQuestions
    .Any(x => x.Key == "PlaceOfBirth" && x.Value == "Madurai")

dynamically using expression builders to pass as the parameter to the extension method. Thanks
