Best way to return a list of different types of same parent class in Java

Using SpringBoot, as REST response, my controller has to return a list of MenuDTO which is a parent class of SimpleMenuDTO and TastingMenuDTO.

I am using ModelMapper to map entity to DTO.

public abstract class MenuEntity {
    private String name;
    private String description;
    private RestaurantEntity restaurant;
}

public class SimpleMenuEntity extends MenuEntity {
    private final Set<MenuSectionEntity> sections = new HashSet<>();
}

public class TastingMenuEntity extends MenuEntity {
    private BigDecimal price;
    private final Set<ProductEntity> products = new HashSet<>();
}

public class MenuDTO {
    private String name;
    private String description;
    private char menuType;
    private Long restaurantId;
}

How can I handle this situation?
I am able to change the entities and DTOs.
