It can be done this way:

  result = Optional.ofNullable(nullableVariable)
                   .map(NullableType::someMethodCall)
                   .orElseGet(() -> fallbackIfNullMethodCall());

This was what I intended to write. Sorry, the HN input box isn't my usual IDE :)

or even:

  result = Optional.ofNullable(nullableVariable)
                 .map(NullableType::someMethodCall)
                 .orElseGet(this::fallbackIfNullMethodCall);

Makes sense, thanks.
