Yes! You can toast your Meringue as a final step once you have it covering your cake, pie, or whatever you're using it on. Toasting it gives it a both a browned appearance and a toasted marshmallow flavor. You can use either the broiler in your oven or a kitchen torch. The broiler gives you a more even golden brown look, but can easily ruin the entire dessert if you leave it in too long. A kitchen torch gives you more control and results in darker, more localized browning. However you toast your meringue, make sure you do it carefully and keep your eyes on it the whole time as it can burn very quickly. To toast it under the broiler, turn the broiler on low, and place your dessert on a higher rack in the oven (you want the dessert to be about 4-6 inches away from the broiler element or top of the oven). Broil for 2-3 minutes, or until the meringue is as browned as you want it. Be ready to remove the dessert immediately once it's done. Alternatively, use a kitchen torch, keeping the flame an inch or two away from the meringue. Torch all over the outside of the dessert until it's as toasted as you want it.
