Here are a few easy ways to make your tuna melt just the way you like it! It’s so fun to try different variations.

- Use Different Cheese: Use your favorite type of cheese here! I always go for classic cheddar, but asiago cheese, jalapeño jack cheese for some spice or Colby jack cheese are all great options!
- More Toppings: For extra texture and flavor try sliced pickles, soft avocados, or lettuce.
- Bread: Try an English muffin, white bread, whole grain bread, whole wheat tortilla, or a thick bagel for different variations of tuna melt sandwiches.
