If I only had 10 minutes a day, I would go to an online newspaper and go to the advice column. There are people who write in for advice/discuss and people in the comments will reply. They're going to be using native expressions and idioms, making references to shared knowledge that everyone there knows. It's also going to be about a wide variety of problems (although a lot tend to be relationship based) which means you'll be able to naturally recall a large variety of words.
Try to read it. If you don't get some words or sentence, skip the sentence for now. Then once you're done with the first read lookup in a dictionary or glosbe and then finally text someone for an explanation to that phrase. (It can be hard to find those friends without visiting a country that speaks your TL and befriending people there).
And then feel free to enter that phrase in your SRS.

I went abroad for 6 months to study my TL (target language) at a foreign language school and would roam campus finding (local) people who don't look busy to help me accomplish this task in real time.
