Break or return from Java 8 stream forEach?

When using external iteration over an Iterable we use break or return from enhanced for-each loop as:

for (SomeObject obj : someObjects) {
   if (some_condition_met) {
      break; // or return obj
   }
}

How can we break or return using the internal iteration in a Java 8 lambda expression like:

someObjects.forEach(obj -> {
   //what to do here?
})
