Keep them in the preheated oven for 10-15 minutes, then to brown faster and nicely, the last 5 minutes let the grill in the oven (if you have it). If you do not have a grill, leave it for another 10 minutes at maximum temperature, it may not brown much but they will be good anyway.
Serve with anything you like - meat, fish, potatoes, rice, etc.
Good appetite!
