Open-Faced Tuna Melt Sandwich

Looking for a super-simple and quick recipe for dinner. Check out this open-faced tuna melt sandwich. The same delicious taste with half the carbs.

If an open-faced approach isn’t your style, try this with an everything bagel. Feel free to spice this up if the kiddos are in using a Serrano Pepper in addition to or instead of the Peppadew Peppers called out in the ingredients list.
