Tuna melt stuffed mini peppers are a delightful and easy-to-make dish that combines the rich flavours of a classic tuna melt with the vibrant crunch of sweet mini peppers. To prepare, simply halve the mini peppers and remove the seeds. Then, mix canned tuna with creamy mayonnaise, a sprinkle of mustard, diced red onion, and a generous helping of grated cheese. Spoon the mixture into the halved peppers and top with a little extra cheese for that irresistible melted finish. Bake until the peppers are tender and the cheese is bubbly and golden. These charming little bites make for a perfect snack, starter, or light lunch, offering a satisfying blend of flavours that will please both tuna aficionados and newcomers alike. Serve with a fresh side salad for a complete meal that's both colourful and nutritious.
