That definitely sounds good to me as a native English speaker. It's also worth considering politeness, because depending on your tone when you say that, it could come off as rude since you would be suggesting that whoever interrupted you did so inappropriately. If the interruption was related to what you were saying, you could make it a little more smooth by saying something like:
Well said. In line with those ideas, the best course of action would be to hire more people.
Thank you for sharing your thoughts. I agree with you and think that the best course of action would be to hire more people.
If the interruption was a digression that was unrelated to your point, you could even say:
As I was saying, the best course of action would be to hire more people.
Or your original statement would work. I would say overall, there is nothing wrong with your original statement. It's just hard to give advice without the context around that conversation.
