That bread looks magical. I have something for you to try. One slice of bread toasted, cold tuna salad, a thick slice of sharp cheddar on top. Turn the broiler on high let if get fire hot. Now with the oven rack as close as you can get it melt that cheese! What you’re aiming for is a warm toast, cold tuna salad, and hot melted cheese. In the meantime imma try what you got goin on here!
