I grew up eating tuna melt sandwiches all the time, and somehow I still never get tired of them. It’s such a quick and tasty lunch option that’s surprisingly high in protein. With over 40 grams of protein per sandwich, it’s a great option when you want something filling and easy to throw together. As a dietitian, I love meals like this because they’re realistic, balanced, and easy to customize.

This sandwich is such a great go-to because I usually have all of the ingredients at home. Canned tuna lasts forever in the pantry, and I don’t need to worry about deli meats going bad. The classic tuna mixture is made with light mayo, chopped celery for crunch, and simple seasonings. Everything gets layered between slices of bread and toasted until the cheese gets melty. It’s simple, but it hits the spot every time.

Making sandwiches customizable and healthier is simple with a few easy swaps. Using a whole wheat or whole grain bread boosts fiber and helps keep you fuller longer. Light mayo reduces the fat and calorie content. Add veggies where you can, whether it’s celery or a handful of spinach. If you’re watching sodium, opt for no salt added tuna and be mindful of how much extra salt you add to the tuna mixture. Tuna, cheese, and bread can all contribute sodium, so those little choices add up.

This tuna melt is one of the best quick lunches when you’re short on time. I love to pair it with a side salad, some sliced veggies, or a piece of fruit. It’s also especially good with some quick pickled onions in it. I hope you enjoy this tuna melt sandwich. Leave a comment below if you have a favorite tuna melt twist of your own!
