Wish I could take credit for this one, but my girlfriend whipped up this beauty for me for dinner. Actually, I don't wish I could take credit. I think this is the way a man was meant to eat a sandwich.
Took some slices of Pepperidge Farm Sourdough bread (the kind that comes in the fancy packaging) and toasted them on broil in the oven, about 2-2.5 minutes one each side (this is the only part I actually helped with).
After the bread was toasted, we put on the tuna mixture. This consisted of a couple cans of tuna fish, about 4-6 spoons of mayo (I love Mayo so this had more than maybe some people might prefer). Also diced a medium sized red onion and threw it in, along with two cut up celery sticks. Season with salt and pepper to taste, you know what you like.
Then put the mixture on the slices of bread, and sprinkled cheddar cheese over the top, and put it back in the oven on broil for about 3-4 minutes, or until the cheese was nice and bubbly. My lady ate hers open faced, preferred mine closed bc Im such a sourdough junkie (and this sourdough, although brand name, did not dissapoint).
Go on and be sandwich.
