Veggie Tomato Sauce

This is a very basic, but yummy pasta sauce I adapted from a special I once had at Vapiano
some time ago.

I diced a zucchini and an eggplant and sautéed them in some olive oil, then added half a bottle of passata di pomodoro, then some sliced black olives and capers and let the whole thing simmer to reduce for 20 mins. Then I added some minced garlic, salt an pepper and- done already!
