Yes! Finally, you could also freeze them for later. Wash the bell peppers, cut them in half, and remove the stems and seeds. Shake off or pat dry the excess water. You can either leave them sliced in half or chop them into strips or chunks. Lay the sliced or chopped bell peppers out on a parchment-lined tray, cover, and freeze them for about 4 to 6 hours. Remove the peppers and transfer them to a freezer-safe bag or container. You freeze for up to four months.
