Wash and chop the peppers and green onions.
Combine the tuna fish, peppers, green onions, and tomato juice.
Place the tuna mixture in a cast iron skillet over the fire, stirring as needed, until the mixture starts to bubble and sizzle and is heated through.
To assemble the tuna melt, split the English muffins in half.
Top the bottom half with a good sized helping of the tuna mixture.
Sprinkle with shredded cheese. We love using Monterey Jack or extra sharp cheddar on our tuna melts.
Grill both the tops and bottoms of the sandwiches on a griddle until the cheese is melted. Be careful not to let the muffins burn.**
Add your favorite taco toppings, like tomatoes and avocado, and serve while warm.
