Tonight, I am making this chicken dish. I don't know what it is called, but it is good

I roast pan chicken legs in no oil. I slowly get rid of the fat the chicken produces. This for about 10-15 minutes. When it is about 10-15 minutes from being all cooked, I lower the heat, add a little bit of olive oil, tomatoes, oinions, rosemary, salt and pepper. I cover with the lid.
This dish is great with pasta or rice.
