Mediterranean beef casserole

I love slow-cooking recipes! They are hearty, but can be made healthy, for quite cheap and require little skills. On the downside, it takes time to nurture such a dish. When I'm cooking for my family, it's always worth the time! And they give it back to me.
This Mediterranean beef casserole is perfect to warm up grey-ish days like today: a tiny tomato-ish, with spring seasoning based on thyme, balsamic vinegar, olives, capers and parsley, and a touch of red wine.

Served on mashed potatoes or pasta, all the family loves this hearty meal! Grown ups: Don't forget to compliment it with a glass of red wine ;)
