Re: heating through stuffed peppers timing. I usually saute what will flavor the filling, add the filling and bake until soft in liquid which takes longer than 30 minutes. I skip the step you have of cooking the peppers separately without filling. If you want, you can make the whole dish in advance and then just warm it up. With a lid or foil covering, that should only take about 20 minutes in a moderate oven. They can be eaten at room temp or cold too.
