We recently tried preparing these tuna stuffed peppers, and we were pleasantly surprised by their flavor. I was even more surprised when i realized how easy it was to prepare them Im sure you always have a spare can of tuna in your kitchen, but it may be difficult to think of different ways of preparing it. This is the perfect opportunity to enjoy something less traditional. Mix the tuna with vegetables and mayo, and use this mix to stuff the peppers before covering them with lots of cheese. Sounds good, right?
