Howto refactor for loop with Service call into Stream?

Question

how would you refactor this code into Streams?

for (ConditionEntity conditionEntity : dbData.getContent()) {
    AdminCondition adminCondition = 
            dataEntityMapper.conditionEntitytoModel(conditionEntity);

    this.myService.addBasicInterest(adminCondition); // <=== this is my Problem
    conditionList.add(adminCondition);
}

I've this so far:

dbData.getContent().stream()
    .map(conditionEntity -> dataEntityMapper.conditionEntitytoModel(conditionEntity))
    .collect(conditionList);

Thx for help!

I would prefer the following solution:

List<ConditionEntity> conditions = dbData.getContent().stream()
        .map(dataEntityMapper::conditionEntitytoModel)
        .collect(Collectors.toList());

conditions.forEach(this::addBasicInterest);
